Actually it isn't, see gl_info->limits.fragment_samplers in
wined3d_adapter_init_limits(). MAX_FRAGMENT_SAMPLERS is used as an upper bound
though and the reason is that there are a number of data structures and
bitmasks in wined3d which are statically sized (the masks would need to be
updated to account for the change, btw). In turn, some of those really
shouldn't depend on the d3d max sampler count (e.g. resource_info in struct
wined3d_shader_reg_maps) but on the max resource count. That's because of
historical reasons i.e. the two values happened to match for d3d <= 9.

In the end, raising MAX_FRAGMENT_SAMPLERS probably isn't the correct fix for
the bug, this would need more work.
