GLES2 on Mesa is advertising the GL_OES_texture_3D extension but the GLSL
compiler seems to get very upset if you try to use it. Attached is an example.
I get these errors with it:

fragment shader info:
0:1(12): warning: extension `GL_OES_texture_3D' unsupported in fragment shader
0:2(22): error: invalid type `sampler3D' in declaration of `tex'
0:7(31): error: `tex' undeclared
0:0(0): error: no matching function for call to `texture3D(, vec3)'

link info:
linking with uncompiled shader
Mesa: User error: GL_INVALID_OPERATION in glUseProgram(program 1 not linked)
Mesa: User error: GL_INVALID_OPERATION in glGetUniformfv(program)
Mesa: User error: GL_INVALID_OPERATION in glUniform(program not linked)

It might be better not to advertise the extension if it's not going to work.
