Subject: [PATCH] OpenGL ES: Fix GLSL version number for 1.00 (#5582)

Wikipedia had it wrong: the spec for the OpenGL ES Shading Language Version 1.00 defines the version preprocessor directive as "#version 100", and _not_ "#version 100 es", like version 3.00+ of the language wants it.

This made the Raspberry Pi with the legacy driver unhappy. Thanks @DangusTaargus for reporting.
