Bug detailed description:
glean/glsl1 have 3 fails with the latest mesa master. This bug report is targeted for the 2nd failure:
  Shader test: 2D Texture lookup with explicit lod (Vertex shader)
  Expected color: 0.25, 0, 0, 0.25
  Observed color: 0, 0, 0, 0

this happens whether or not INTEL_NO_TTM set.

Reproduce steps:
run glean case glsl by:
./glean -r ResultDir -t glsl1
Comment 1 Zou Nan hai 2008-01-03 01:26:53 UTC
This program is doing tex fetch in vertex shader which is not supported in current driver architect. We may implement it later but not in current time frame
Comment 2 Roland Scheidegger 2008-01-04 05:11:57 UTC
The driver should probably set Const.MaxVertexTextureImageUnits to 0 in this case (which is a legal value).

Mass reopen.  The "LATER" resolution is lame, I'm deleting it.  Consider LATER to have arrived.
Comment 5 Ian Romanick 2008-12-08 17:05:39 UTC
This bug was fixed in July by commit 43346fb1fb43f91cb3e90d84b442dc08d6c9550d.

Mass version move, cvs -> git
