[navaraf] 14288: Merge from HEAD: r14246

Merge from HEAD: r14246
- Move WINDOWOBJECT_NEED_INTERNALPAINT flag handling to NtGdiBeginPaint.
- Fix IntGetPaintMessage to not return TRUE when no message was
returned.
- IntIsWindowDirty shouldn't check for the WINDOWOBJECT_NEED_NCPAINT
flag (at least not now).
