I mistakenly introduced a bug in my recent PR regarding template
constants, in which a -1 that was supposed to appear outside of an abs()

This PR attempts a number of improvements to the sample rendering (in the song editor, automation editor, AudioFileProcessor, SlicerT, etc) in LMMS:
Thumbnails: Samples are aggregated into a set of thumbnails of multiple resolutions. The smallest larger thumbnail is then chosen for rendering during sample drawing. Each set of thumbnails is stored with its sample file metadata in an unordered_map, so that duplicate samples will use the same set of thumbnails.
Partial rendering: additionally, this PR only renders the portions of the sample clips visible to the viewer to save rendering time.
* Experimental sample thumbnail

samples (~20 minutes)
* Simplify sample thumbnail cache handling in constructor
* Call drawLines instead of drawLine in a loop
QPainter::drawLine calls drawLines with a line count of 1. Therefore, calling drawLine in a loop means we are simply calling drawLines a lot more times than necessary.
* Bump up AggregationPerZoomStep to 10 again
Thought using 2 would help performance (when rendering). Maybe it does, but it's still quite slow when rendering a bunch of thumbnails at once.
* Fix off-by-one error when constructing Thumbnail from buffer
* Fix crash when viewport is not in bounds
* Apply performance improvements
Performance in the zoomOut function was bad because of the dynamic memory allocation. Huge chunks of memory were being allocated quite often, casuing a ton of cache misses and all around slower performance. To fix this, all the necessary downsampling is now done within the for loop and handled one pixel after another, instead of all at once.
To further avoid allocations in the draw call, the change to use drawLines has been reverted.
We now pass VisualizeParameters by value (it is only 64 bytes, which will fit quite nicely in a cache line, which is more benefical than reaching for that data by reference to some other part of the code).
After applying these changes, we are now practically only bounded by the painting done by Qt (according to profiling done by Valgrind). Proper use of OpenGL could resolve this issue, which should finally make the performance quite optimal in variety of situations.
* Apply minor changes
Update copyright and unused functions. Move in newly created thumbnail into the cache instead of copying it.
* Use C++20's designated initializers
* Create param right before visualizing
* Fix regressions with reversing
* Fix incorrect rendering in AFP and SlicerT
* Move MaxSampleThumbnailCacheSize and AggregationPerZoomStep into implementation file
* Remove static keyword
* Remove getter and setter for peak data

* Fix rendering for Vectorscope
The rendering of the Vectorscope is broken on Wayland if the size of the
Vectorscope is increased. This is caused by using a `QImage` to render
the scope traces which is then scaled up.
Introduce a new way to paint the vector scope (goniometer) which simply
paints lines or points that progressively get dimmer and which does not
make use of a QImage anymore.
It supports the following features:
* Log mode
* Zooming
* Rendering the drawing performance
* Selecting a different color for the traces
It does not support:
* HQ Mode: The new implementation provides a performance that's
equivalent to Non-HQ mode and look similar or better than the HQ mode.
* Blurring of old data
* Persistence: Might be implemented by using a factor for the dimming
Rendering of the samples/trances uses the composition mode "Plus" so
that overlapping elements will appear like adding brightness. Painting
the grid and lines is done using the normal composition mode "Source
Over" so that it simply replaces existing pixels.
Painting of the lines/points and the grids and lines is done in a
"signal space", i.e. a transform where elements in the interval of
[-1, 1] feel "natural". The text is painted in "widget space".
* Remove old implementation
Remove HQ mode and persistence. Also remove the legacy option again.
This removes the models, loading, saving and the GUI controls.
Remove all unnecessary members from `VectorView`, adjust the
constructor. Move the implementation of `paintLinesMode` into
`paintEvent`. Remove methods `paintLegacyMode` and `paintLinesMode`.
* Move colors into VectorView
Move the colors out of `VecControls` into `VectorView` as they are
related to presentation.
* Remove friend relationship to VectorView
Remove a friend relationship to `VectorView` from `VecControls` by
introducing const getters for the models.
* Remove VectorView::m_visible
Remove the unnecessary member `m_visible` from `VectorView`. It was not
initialized and only written to but never read.
* Make Vectorscope themeable
Make the Vectorscope themeable by introducing Qt properties for the
relevant colors.
The default theme gets the values from the code whereas the classic
theme gets a trace with amber color.
* Rename m_colorFG
Rename `m_colorFG` to `m_colorTrace`. Adjust the Qt property
accordingly.
Remove local variable `traceColor` from paint method and use member
`m_colorTrace` directly.
* Remove m_colorOutline
Remove unused member `m_colorOutline`.
* Fix horizontal lines on silence
Fix the horizontal lines that are rendered on silence. They seem to be
produced when rendering lines that start and end at the same point.
Therefore we only draw a point if the current and last point are the
same.
* Add some margin to the VectorView
Add some margin to the rendering of the `VectorView` so that the circle
does not touch the bounary of the widget.
* Clean up the layout of the Vectorscope
Clean up the layout of the Vectorscope. The checkboxes are not put on
top of the vector view anymore but are organized in a horizontal layout
beneath it. This gives a much tidier look.
* Compile in C++20 mode
* Fix implicit lambda captures of `this` by `[=]`
Those implicit captures were deprecated in C++20
* Silence MSVC atomic std::shared_ptr warning
Unfortunately std::atomic<std::shared_ptr> (P0718R2) is not supported by
GCC until GCC 12 and still is not supported by Clang or Apple Clang, so
it looks like we will continue using std::atomic_load for the time being

Historically, the PeakController has had issues like attack/decay knobs
acting like on/off switches, and audio artifacts like buzzing or
clicking. This patch aims to address those issues.
The PeakController previously used lerp (linear interpolation) when
looping through the sample buffer, which was in updateValueBuffer. This
lerp utilized attack/decay values from control knobs. This is not the
correct place to utilize attack/decay because the only temporal data
available to the function is the frame and sample size. Therefore the
coefficient should simply be the sample rate instead.
Between each sample, processImpl would set m_lastSample to the RMS
without any sort of lerp. This resulted in m_lastSample producing
stair-like patterns over time, rather than a smooth line.
For context, m_lastSample is used to set the value of whatever is
connected to the PeakController. The basic lerp formula is:
m_lastSample = m_lastSample + ((1 - attack) * (RMS - m_lastSample))
This is useful because an attack of 0 sets m_lastSample to RMS, whereas
an attack of 1 would set m_lastSample to m_lastSample. This means our
attack/decay knobs can be used on a range from "snap to the next value
immediately" to "never stray from the last value".
* Remove attack/decay from PeakController frame lerp.
* Set frame lerp coefficient to 100.0 / sample_rate to fix buzzing.
* Add lerp between samples for PeakController to fix stairstep bug.
* The newly added lerp utilizes (1 - attack or decay) as the
coefficient, which means the knobs actually do something now.
* Remove QTextCodec
QTextCodec was removed from Qt6 and is only available through the
Qt5Compat module.
QTextCodec was only used by the HydrogenImport plugin when importing old
Hydrogen files that were saved using TinyXML before it supported UTF-8.
HydrogenImport would use QTextCodec to try to get the current encoding
from the locale, and then use that as a best guess for interpreting the
XML data in the unspecified encoding it was saved in. None of this was
ever reliable, since the encoding of the computer that saved the
Hydrogen file might not be the same as the computer running LMMS and
importing that file.
There is no good solution here, so I decided to simply assume the old
Hydrogen files are UTF-8 encoded. The worst that can happen is someone's
ancient Hydrogen files containing non-ASCII text of some random encoding
becomes mojibake'd after importing into LMMS, which is something that
already could have happened.
* Clean up a little
Remove the member `PluginView::m_isResizable` and it's associated method `setResizable`. Turn `isResizable` into a virtual method.
The reasoning is that whether or not an effect can be resized depends on its implementation. Therefore does not make sense to have a method like `setResizable`. If the underlying implementation does not support resizing then it would not make sense to call `setResizable(true)`. So `isResizable` now describes the underlying ability of a plugin to resize. It's then up to the clients of that method to decide how to treat the result of `isResizable`, i.e. if they want to make use of the ability to resize or not.

* Fix text problem in Vectorscope
Fix a problem with cutoff text in Vectorscope. During the constructor
call of `LedCheckBox` the method `LedCheckBox::onTextUpdated` is
triggered which sets a fixed size that fits the pixmap and the text.
After instantiating the two instances in `VecControlsDialog` the
constructor then set a minimum size which overrode the fixed size that
was previously set. This then led to text that was cutoff.

Defines `fpp_t` and `f_cnt_t` to be of `size_t` within `lmms_basics.h`. Most of the codebase used `fpp_t` to represent the size of an array of sample frames, which is incorrect, given that `fpp_t` was only 16 bits when sizes greater than 32767 are very possible. `f_cnt_t` was defined as `size_t` as well for consistency.

Fix a buzzing sound in Monstro's 2nd oscillator. It was introduced with
commit c2f2b7e0d7.
The problem was caused by checking if `len_r` is not equal to 0 instead of
checking `pd_r`.
* Remove the struct StereoSample
Remove the struct `StereoSample`. Let `AudioEngine::getPeakValues` return a `sampleFrame` instead.
Adjust the calls in `Mixer` and `Oscilloscope`.
* Simplify AudioEngine::getPeakValues
* Remove surroundSampleFrame
Some code assumes that `surroundSampleFrame` is interchangeable with `sampleFrame`. Thus, if the line `#define LMMS_DISABLE_SURROUND` is commented out in `lmms_basics.h` then the code does not compile anymore because `surroundSampleFrame` now is defined to be an array with four values instead of two. There also does not seem to be any support for surround sound (four channels instead of two) in the application. The faders and mixers do not seem to support more that two channels and the instruments and effects all expect a `sampleFrame`, i.e. stereo channels. It therefore makes sense to remove the "feature" because it also hinders the improvement of `sampleFrame`, e.g. by making it a class with some convenience methods that act on `sampleFrame` instances.
All occurrences of `surroundSampleFrame` are replaced with `sampleFrame`.
The version of `BufferManager::clear` that takes a `surroundSampleFrame` is removed completely.
The define `SURROUND_CHANNELS` is removed. All its occurrences are replaced with `DEFAULT_CHANNELS`.
Most of the audio devices classes, i.e. classes that inherit from `AudioDevice`, now clamp the configuration parameter between two values of `DEFAULT_CHANNELS`. This can be improved/streamlined later.
`BYTES_PER_SURROUND_FRAME` has been removed as it was not used anywhere anyway.
* Make sampleFrame a class
Make `sampleFrame` a class with several convenience methods. As a first step and demonstration adjust the follow methods to make use of the new functionality:
* `AudioEngine::getPeakValues`: Much more concise now.
* `lmms::MixHelpers::sanitize`: Better structure, better readable, less dereferencing and juggling with indices.
* `AddOp`, `AddMultipliedOp`, `multiply`: Make use of operators. Might become superfluous in the future.
* More operators and methods for sampleFrame
Add some more operators and methods to `sampleFrame`:
* Constructor which initializes both channels from a single sample value
* Assignment operator from a single sample value
* Addition/multiplication operators
* Scalar product
Adjust some more plugins to the new functionality of `sampleFrame`.
* Adjust DelayEffect to methods in sampleFrame
* Use composition instead of inheritance
Using inheritance was the quickest way to enable adding methods to `sampleFrame` without having to reimpement much of `std::array`s interface.
This is changed with this commit. The array is now a member of `sampleFrame` and the interface is extended with the necessary methods `data` and the index operator.
An `average` method was added so that no iterators need to be implemented (see changes in `SampleWaveform.cpp`).
* Apply suggestions from code review

* Fix warnings: zeroing non-trivial type
Fix several warnings of the following form:
Warnung: »void* memset(void*, int, size_t)« Säubern eines Objekts von nichttrivialem Typ »class lmms::sampleFrame«; use assignment or value-initialization instead [-Wclass-memaccess]
* Remove unnecessary reinterpret_casts
Remove some unnecessary reinterpret_casts with regards to `sampleFrame` buffers.
`PlayHandle::m_playHandleBuffer` already is a `sampleFrame*` and does not need a reinterpret_cast anymore.
In `LadspaEffect::processAudioBuffer` the `QVarLengthArray` is now directly initialized as an array of `sampleFrame` instances.
I guess in both places the `sampleFrame` previously was a `surroundSampleFrame` which has been removed.
* Clean up zeroSampleFrames code
* Fix warnings in RemotePlugin
Fix some warnings related to calls to `memcpy` in conjunction with`sampleFrame` which is now a class.
Add the helper functions `copyToSampleFrames` and `copyFromSampleFrames` and use them. The first function copies data from a `float` buffer into a `sampleFrame` buffer and the second copies vice versa.
* Rename "sampleFrame" to "SampleFrame"
Uppercase the name of `sampleFrame` so that it uses UpperCamelCase convention.
* Move SampleFrame into its own file
Move the class `SampleFrame` into its own class and remove it from `lmms_basics.h`.
Add forward includes to all headers where possible or include the `SampleFrame` header if it's not just referenced but used.
Add include to all cpp files where necessary.
It's a bit surprising that the `SampleFrame` header does not need to be included much more often in the implementation/cpp files. This is an indicator that it seems to be included via an include chain that at one point includes one of the headers where an include instead of a forward declaration had to be added in this commit.
* Return reference for += and *=
Return a reference for the compound assignment operators `+=` and `-=`.
* Explicit float constructor
Make the constructor that takes a `float` explicit.
Remove the assignment operator that takes a `float`. Clients must use the
explicit `float` constructor and assign the result.
Adjust the code in "BitInvader" accordingly.
* Use std::fill in zeroSampleFrames
* Use zeroSampleFrames in sanitize
* Replace max with absMax
Replace `SampleFrame::max` with `SampleFrame::absMax`.
Use `absMax` in `DelayEffect::processAudioBuffer`. This should also fix
a buggy implementation of the peak computation.
Add the function `getAbsPeakValues`. It computes the absolute peak
values for a buffer.
Remove `AudioEngine::getPeakValues`. It's not really the business of the
audio engine. Let `Mixer` and `Oscilloscope` use `getAbsPeakValues`.
* Replace scalarProduct
Replace the rather mathematical method `scalarProduct` with
`sumOfSquaredAmplitudes`. It was always called on itself anyway.
* Remove comment/TODO
* Simplify sanitize
Simplify the `sanitize` function by getting rid of the `bool found` and
by zeroing the buffer as soon as a problem is found.
* Put pointer symbols next to type
* Code review adjustments
* Remove "#pragme once"
* Adjust name of include guard
