+Subject: 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
+e7085310d6d594823d0ed491fa8bdbd99dec4932 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.
