Complete small program to demonstrate problem. Compile instructions in source

glVertexAttribDivisor does not work on a Fedora 21 system with Intel HD
Graphics 5500, Mesa 10.5.8, core profile version 3.3. Attribute with divisor
set to 1 (per instance) appears to be still incrementing per vertex.

not mentioned in release notes for 10.5.9, 10.6, or 10.6.1; does not appear in
