Looking at the test results... any idea what it's actually doing?
Ignoring alpha and using 1.0? Using garbage? Other?
FWIW this fails for GL_DOT3_RGBA_EXT but works for GL_DOT3_RGB_EXT
[according to glean's texCombine test]. (I suspect the existing
GL_DOT3_RGBA/RGB had a similar behavior.) I'm testing in a slightly
unsupported environment - the NV25 graph class running on a NV34
(GeForce FX 5200), but I think

GL_DOT3_RGB_EXT and GL_DOT3_RGBA_EXT. are nearly identical to
GL_DOT3_RGB and GL_DOT3_RGBA. The only difference is the _EXT
versions do not apply the post-scale. Just smash logscale to 0 so
that RC_OUT_SCALE_1 is always used.
