Wolfgang Bauer 9af659c73e Fix ibeam and underline cursor rendering
Summary:
Since anti-aliasing was enabled in the painter, coordinates need to
be shifted half a pixel so that they align with the pixel grid,
otherwise the result gets "blurred" due to the anti-aliasing.
And as parts of the blurred shape leak outside the cursor rectangle,
this also leaves artifacts when the cursor moves or blinks as these
parts are not cleared.

This is basically the same as commit
e7085310d6 for the
standard block cursor.

BUG: 402589

Test Plan:
- Switch cursor shape to "I-Beam" or "Underline" in the "Advanced"
profile settings

The cursors are a single line again now, before they were blurred by
anti-aliasing.

Screenshots:
Before:
{F6656366}
{F6656370}

After:
{F6656371}
{F6656373}

Also, there are no more artifacts when the cursor is moved or
cursor blinking is enabled.

Konsole - KDE's Terminal Emulator
==================================

Konsole is a terminal program for KDE.

As well as being a standalone program, it is also used by other KDE programs
such as the Kate editor and KDevelop development environment to provide easy
access to a terminal window. Konsole's features and usage are explained and
illustrated in the Konsole handbook, which can be accessed by browsing to
"help:/konsole" in Konqueror.
