wm4 d78bde15ab vo_opengl_old: reject 9-15 bit formats if textures have less than 16 bit
For 9-15 bit material, cutting off the lower bits leads to significant
quality reduction, because these formats leave the most significant bits
unused (e.g. 10 bit padded to 16 bit, transferred as 8 bit -> only
2 bits left). 16 bit formats still can be played like this, as cutting
the lower bits merely reduces quality in this case.

This problem was encountered with the following GPU/driver combination:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 9.0.1

It appears 16 bit support is rather common on GPUs, so testing the
actual texture depth wasn't needed until now. (There are some other Mesa
GPU/driver combinations which support 16 bit only when using RG textures
instead of LUMINANCE_ALPHA. This is due to OpenGL driver bugs.)

Compiling with full features requires development files for several
external libraries. Below is a list of some important requirements. For
more information see the output of './configure --help' for a list of options,
or look at the list of enabled and disabled features printed after running
'./configure'. If you think you have support for some feature installed
but configure fails to detect it, the file config.log may contain information
about the reasons for the failure.

Libraries specific to particular video output methods
(you'll want at least one of VDPAU, GL or Xv):
 - libvdpau (for VDPAU output, best choice for NVIDIA cards)
 - libGL (OpenGL output)
 - libXv (XVideo output)
general:
 - libasound   (ALSA audio output)
 - various general X development libraries
 - libfreetype (for libass)
 - libfontconfig (for libass)
 - libass
 - FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)

Most of the above libraries are available in suitable versions on normal
Linux distributions. However FFmpeg is an exception (distro versions may be
too old to work at all or work well). For that reason you may want to use
the separately available build wrapper that first compiles FFmpeg libraries
and libass, and then compiles the player statically linked against those.
