Carl J. Bialorucki bd270f07f3 [0.4.15][NTUSER] Handle window update region larger than the current window in clip region (#7731) 
CORE-18206 CORE-18799 CORE-19371

Fixes infinite loop of:
  err: Message WM_PAINT count 1 Internal Paint Set? FALSE

The symptom appears in the following scenario (as reported in CORE-18799):

A program (game) runs at a small resolution (e.g. 640 x 480), but the
game window gets invalidated at a larger size (e.g. 1152 x 864 screen
resolution) before switching to the smaller (640 x 480) size.
Because of this, the window's update region is larger than the current
window so only the 640 x 480 region gets validated leaving the remaining
region invalid. This causes the recurring WM_PAINT messages because there
is no way to invalidate the remaining area.

This is a backport of commit:
