Log:

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.
