Comment(by markk):

 (In [23066]) Branch libmythui-osd: MythQImagePainter improvements.

  - Use a fast, copy based painting mode when the area to be painted is
 clear and hence no blending is needed. To work properly, this needs the
 QImage format to be Format_ARGB32_Premultiplied and hence this probably
 breaks the ChromaKey OSD for the time being. The pre-multiplied format
 is also generally faster.

  - Add a Clear method to clear areas of the paint image prior to re-
 sub-classed for the YV12 painter.
