fz_shdr_cbak_refl_pre_render

Description

Reflection shader pre_render function (Optional). This function is called once before the start of each rendering. It is expected to precompute information that will be used by the function. Typically, the pre-render function will allocate a data structure, fill it with precomputed information and pass the pointer of the structure back to formZ via the function argument. This pointer will be passed back into the function and also the function, which should de-allocate the structure.
