Use absolute, not relative canvas position when logging errors

checkCanvasRectColor used to log position relative to the corner of the
rectangle being checked. Logging absolute canvas position makes more
sense when analyzing errors, so switch to that in the new and 1.0.2
versions of the conformance suite.
fix some request from Ken Russell about the new test added.

Fixed mismatched uniform precisions between vertex and fragment shaders causing demos to fail to load in Chrome on Windows. The conformance test glsl/misc/shader-with-global-variable-precision-mismatch.html (currently failing on some platforms in Chrome) already covers this case.

Fix interpolation in reference image generation for GLSL fragment shader tests

Emulate the barycentric coordinate interpolation done by the GPU in the
reference renderings for the fragment shader tests. Previously color
values for fragments were computed per-fragment using the bilinearly
interpolated texCoord value, which did not match up with the barycentric
interpolation from the 3 nearest vertices' color values.

This is a bug fix to the conformance suite, so the fix has been
backported as far back as version 1.0.1.
