a not-quite cosmetic problem in shader handling

[galtgendo]

There's a little bit of code, that while works, it could use a bit of semi-trivial error handling.

In ruby/video/opengl/surface.hpp, you should consider adding if (fooVertex != -1) for all three glEnableVertexAttribArray/glVertexAttribPointer blocks and the three final glDisableVertexAttribArray calls.

Without the condition, the calls fail silently, but why make them in the first place then.

This is something that should be posted in the upstream repository. This one is for libretro issues only.

... One problem with that: reporting issues on main is restricted to contributors only.
