Fix ES2 shaders

Add missing floating point precision qualifiers.

'#extension OES_standard_derivatives : require' somehow doesn't pass the GLSL compiler,
however '#extension GL_OES_standard_derivatives : enable' does.

Currently works on ARM's Mali-400 MP, NV Tegra still don't show a picture.

TODO: More in depth evaluation.
