We were copying the source stencil data onto the destination depth data.
Fixes piglit copyteximage other than 1D_ARRAY.

I suspect the problem are these lines in setup_glsl_generate_mipmap():

Which version of Mesa, and which driver?
I tested with Mesa/master and the 9.1 branch and didn't see this problem.
However, I did find a problem when the libtxc_dxtn.so library wasn't present.

When a fake front buffer is in use, if we request the front buffer
(using screen->dri2.loader->getBuffersWithFormat()), the X server
copies the real front buffer to the fake front buffer and returns the
fake front buffer. We sometimes make redundant requests for the front
buffer (due to using a si
The patch that follows will fix a bug that prevents
intel_flush_front() from being called often enough. In doing so, it
will create a situation where intel_flush_front() during the initial
call to glXMakeCurrent(). In this circumstance, ctx->DrawBuffer
hasn't been initialized yet and is NULL. Fo

Okay I now understand why Frank would want to run away, this is
my attempt at fixing the CVE out of bounds access to constants
outside the range. This attempt converts any illegal constants
to constant 0 as per the GL spec, and is undefined behaviour.
