Is there any rational for the 512 byte alignment in this macro?I think that Gerk found a small performance improvement with a 512-
This is used to allocate main-memory copies of texture images, so the numbers add up pretty quickly...
I can't think of any reason to go beyond 16 or at most 32 byte alignment from a cpu/caching perspective, and these buffers aren't visible to hardware (which can have more stringent requirements).

texture allocation he could override whatever default alignment is used.
Feel free to reduce or remove the alignment.
