This is hrev54101.
In some situations app_server screen back buffer is flushed before drawing
is finished causing flickering artifacts:
1. When moving cursor (#15645).
2. When move window (#15631).
3. When BView::DrawBitmap is called on overlapping window with lower
z-order (#15574).
I created test program that helps to catch bug. Nested red, green and blue
rectangles should be displayed. Flickering or artifacts means that this
bug is triggered.
