* Rework PianoRoll paintEvent + some extras * Split out PositionLine class to own file * Refactor PianoRoll Q_PROPERTYs * Reduce code by using Q_PROPERTY's MEMBER function and removing getter/setter functions After looking at the getters and setters, they did nothing different than what direct access would allow. Nothing outside of PianoRoll used the public functions as well. Considering these factors we can reduce the number of functions by 2x the number of Q_PROPERTIES, and go with direct access instead. * Remove need for keyboard pixmaps With the recent change to allow zooming vertically, aligning pixmaps is a PITA. Since we have themes which can take brushes and colors, it would be simpler to take a solid color or a gradient with some extra style properties to resize the keys and text colors. While it will slightly be a downgrade from pixmaps since they can be anything really, this will allow us to customize the piano roll further moving forward. * Added the ability to update margins for TimeLineWidget and StepRecorderWidget These take a X coordinate, which was hardcoded to WHITE_KEY_WIDTH, and never looked back. Now we can adjust on the fly if we need to. Currently this just allows us to shift the left margin to the style-defined white key width. * Fix phantom pixmaps when PianoRoll not focused * Update PositionLine class changes related to #5543
