Done in r26951 for plain "r210" (aka RGB30).

Still TODO:

  • actually test on 30-bit displays and verify that the extra 2 bits of pixel depth are used
  • convert GBRP10 to r210 via csc_cython so that we can use h264
  • maybe also add FORMAT_RGB16_565?

The resulting picture is only half the height!? (reading more segfaults)
Is it the decoder or the csc that is wrong?

Summary: handle 30-bit pixels in cairo backend → handle 16 and 30-bit pixels in cairo backend

r26956 + r26957 adds support for 16-bit BGR565 pixels (aka cairo.FORMAT_RGB16_565)

r26960 does the conversion from GBRP10 to r210 which allows us to handle 10-bit video in both opengl and non-opengl cases.

All looks good, except on win32 (headerbar bug): ticket:2539#comment:20.
