util: Add array_index support to [vertex data] (v2)

Graphics / Mesa 3D Graphics Library / Piglit - Andres Gomez [igalia.com] - 17 May 2016 03:38 UTC

This allows data to be set for arbitrary array sized attributes in shader runner.

For example to set mat2x3[2]: attname[0]/mat2x3/3/1 attname[0]/mat2x3/3/2 attname[1]/mat2x3/3/1 attname[1]/mat2x3/3/2

The syntax has been extended so the recommended type to specify in the [vertex data] header line is the GLSL corresponding one, not just "float", "double", "int" or "uint".

In any case, the extended syntax is backward compatible so it is still possible to specify a vec3 attribute like: attname/float/3

In addition to the now recommended format: attname/vec3/3

v2: Added more verbose comments and documentation as requested by Alejandro Piñeiro.
