<pre>The current implementation of ARB_get_program_binary is incomplete and
currently violates the spec.
Specifically these are the major issues:
* glGet with GL_NUM_PROGRAM_BINARY_FORMATS is not implemented, it should return
a at least 1.
* glGet with GL_PROGRAM_BINARY_FORMATS is not implemented, it should return a
list with a single binaryFormat.
* glGetProgramBinary succeeds with a binary length of zero, and also does not
set binaryFormat to a valid value, it should always succeed and set
binaryFormat to the value returned by GL_PROGRAM_BINARY_FORMATS.
* glProgramBinary always fails with GL_INVALID_OPERATION despite program being
valid, it should always succeed if binaryFormat is correct, and return
GL_INVALID_ENUM if not. Additionally it should always set GL_LINK_STATUS to
GL_FALSE to indicate the program will need to load source anyway.
If these are not to be implemented ARB_program_binary and GL 4.1+ support
should not be advertised by Mesa.</pre>
