nanogui: Thread: [PATCH 1/1] Fix GsWpDrawBackgroundPixmap

Hi,

this is my first patch to microwin:

[PATCH 1/1] Fix GsWpDrawBackgroundPixmap, to allow GrClearArea work
properly when the background of the window is a pixmap

Without this change GrClearArea cleared to the background pixmap not
the defined area but the are from the start point (x, y) to the end of
the screen.

Any comments are welcome )
