The previous texture_memory_alloc.hpp was written based on an incorrect understanding of the "32-bit" and "64-bit" texture memory address mapping. The primary motivation is to rearrange the texture memory address map so that "textures" (64-bit access) do not overlap with 32-bit accesses, such as REGION_BASE or PARAM_BASE.
