[mythtv] [PATCH] Fix background origin on transparent widgets

[Kevin Kuphal]

This patch fixes the background origin on "transparent" widgets (most 
noteably visible on the "Pre-scaling" window) so that the widget 
background is offest to match it's parent background. 

Without this the background 0,0 is set to the widget 0,0 and it looks 
funny because the parent has the same background and now you have two 
identical pixmaps overlapping (parent background and widget 
background).  After the patch, the widget background is offset to match 
the parent so the transparency looks complete.
