Support multisample arrays in shader programs
Browse files Browse the repository at this point in the history 
The added tests check that using textureSize() and texelFetch() on
textures with a fixed point format return expected results. texelFetch
is also covered for integer format textures.

dEQP GLES 3.1 tests also cover a variety of multisampled array texture
formats.

BUG=angleproject:2775
TEST=angle_end2end_tests, angle_deqp_gles31_tests
