[Mesa-dev] Gen7 HiZ regression

[Kenneth Graunke]

Hi Chad,

I tracked down the Gen7 HiZ regression a little bit.  It turns out it 
isn't HiZ, since

$ INTEL_HIZ=0 ./bin/fbo-clear-formats GL_ARB_depth_texture

still fails.  However, reverting commit bebc91f0f3a1f2d19d36a7
(i965: Replace references to stencil region size with buffer size) fixes 
the test.  (You also have to revert 254b24f195110 so it compiles.)

I'll leave it to you to figure out why...
