* shader is used with fixed function vertex processing we're fine too because fixed function
* vertex processing doesn't use any samplers. If fixed function fragment processing is
* used we have to make sure that all vertex sampler setups are valid together with all
* possible fixed function fragment processing setups. This is true if vsamplers + MAX_TEXTURES
* <= max_samplers. This is true on all d3d9 cards that support vtf(gf 6 and gf7 cards).
* dx9 radeon cards do not support vertex texture fetch. DX10 cards have 128 samplers, and
* dx9 is limited to 8 fixed function texture stages and 4 vertex samplers. DX10 does not have
* a fixed function pipeline anymore.
*
* So this is just a check to check that our assumption holds true. If not, write a warning
* and reduce the number of vertex samplers or probably disable vertex texture fetch.
