/**
* This bit extends the set of GL_MAP_*_BIT enums.
*
* When calling intel_miptree_map() on an ETC-transcoded-to-RGB miptree or a
* depthstencil-split-to-separate-stencil miptree, we'll normally make a
* tmeporary and recreate the kind of data requested by Mesa core, since we're
* temporary and recreate the kind of data requested by Mesa core, since we're
* satisfying some glGetTexImage() request or something.
*
* However, occasionally you want to actually map the miptree's current data
