This prevents developer surprise at seeing a GL_DEPTH_COMPONENT texture have stencil bits, and avoids the metaops path accidentally copying stencil bits around in glCopyTexImage(GL_DEPTH_COMPONENT) (and being broken because swrast's glReadPixels(GL_UNSIGNED_INT_24_8) is broken). Reproduce steps: ---------------- 1. start X 2. ./oglconform -z -s -suite all -v 2 -D 115 -test fbo renderToRb.1FBOIterateIntFormatsDepth

I made a mistake. This case first failed on mesa master with bug 39253 tracked( https://bugs.freedesktop.org/show_bug.cgi?id=39253). It still fails on mesa master now. It failed on mesa 7.11 when the bad commit 57a6e6092fc8d was imported in 7.11. *** This bug has been marked as a duplicate of bug 39253 ***
