Comment (by mark_kendall at btinternet.com):

 Opengl OSD performance improvements.

 1. Rather than converting the YUV OSD frame each time it is displayed, we
 render into a framebuffer and only update when necessary. This is a major
 performance improvement, esp. if used in conjunction with the new option
 to enable/disable the OSD fade.

 2. Make sure the viewport is set for the osd filter (it otherwise defaults
 to 1920x1080).
