/* The ATIFS code does not support pixel shaders currently, but we have to provide a state handler
* to call shader_select to select a vertex shader if one is applied because the vertex shader state
* may defer calling the shader backend if the pshader state is dirty.
*
* In theory the application should not be able to mark the pixel shader dirty because it cannot
* create a shader, and thus has no way to set the state to something != NULL. However, a different
* pipeline part may link a different state to its pixelshader handler, thus a pshader state exists
* and can be dirtified. Also the pshader is always dirtified at startup, and blitting disables all
* shaders and dirtifies all shader states. If atifs can deal with this it keeps the rest of the code
* simpler.
