Brad, it would be super helpful for me to understand what is going on if you
could run a gdb session and print:

a) the values of the parameters passed to compute_src2dst_component_mapping
_after_ it has been called (they all are 4-element arrays, the last one is an
out parameter so that is why I need the values after the call has been done)

b) The following input parameters for the call to _mesa_swizzle_and_convert
right after: src_type, dst_type, dst_num_channels, src_num_channels,
normalized, width.

Could you do this?
