/** Implementation of (Test 10) for texture_cube_map_array extension. Test description follows:
 *   Make sure shaders can correctly query the size of cube-map array textures
 *   bound to active texture or image samplers.
 *
 *   Category:           Coverage,
 *                       Optional dependency on EXT_geometry_shader;
 *                       Optional dependency on EXT_tessellation_shader;
 *   Suggested priority: Must-have for the texture part;
 *                       Must-have for the image part;
 *
 *   Make sure textureSize() (both shadow and normal cases) GLSL functions
 *   return correct values for cube-map array textures.
 *   Make sure imageSize() returns correct values for image units, to which
 *   cube-map array textures have been bound.
 *
 *   All supported shader types should be considered for the purpose of the
 *   test.
 *
 *   The results should be XFBed back to test implementation for verification
 *   in case of geometry & tessellation shaders & vertex shaders.
 *   For compute shaders, the size should be stored to an image of
 *   1x1 resolution and of GL_RGBA32UI internalformat.
 *   Fragment shaders should store the texture size by writing it to
 *   an output variable defined in the fragment shader. A GL_RGBA32UI
 *   texture of 1x1 resolution should be used as a draw buffer.
 *
 *   The following texture resolutions should be used
 *       { 64,  64,  6},
 *       {128, 128, 12},
 *       {256, 256, 12},
 *       { 32,  32, 18}
 *   Both immutable and mutable textures should be checked.
