[Piglit] [PATCH 2/2] arb_shading_language_420pack: Added some few more struct initializing tests

[Andres Gomez]

This set focus on checking invalid structs
initializations. Specifically, adds a test to check that only implicit
conversions are perform and vector conversions of the type vec3 to
vec2 through dropping the z component are not allowed.
