[Piglit] [PATCH 13/23] Port texture glsl tests from Glean to Piglit.

[Fabian Bieler]

The following tests weren't ported because the functionality is already
tested in existing piglit tests:

"texture2D()"
shaders/glsl-fs-texture2d.shader_test

"texture2D(), with bias"
shaders/glsl-fs-texture2d-bias.shader_test

"2D Texture lookup with explicit lod (Vertex shader)"
shaders/glsl-fs-texturelod-01.shader_test

"texture2DProj()"
shaders/glsl-fs-texture2dproj.shader_test

"shadow2D(): [1234]"
spec/glsl-1.10/execution/samplers/glsl-fs-shadow2D-*.shader_test
