From tests/spec/glsl-1.10 extend variable-index-read.sh so that
it can also correctly generates variable index read tests that
support glsl-es-1.00.

1.00 added as a valid parameter to generated tests for glsl-es-1.00.

For 1.00 tests the vertex shader an orthographic projection is
applied since ortho during the test portion isn't supported on
OpenGL ES.

For 1.00 tests the fragent shader specifies default precision.

For 1.00 tests emit in the [require] section the correct
GLSL ES and GL ES settings.
