Tests the queryable state from ARB_texture_view extension is correct.
Includes GL_TEXTURE_IMMUTABLE_LEVELS,GL_TEXTURE_VIEW_MIN_LEVEL,
GL_TEXTURE_VIEW_NUM_LEVELS, GL_TEXTURE_IMMUTABLE_FORMAT.
Tested on Nvidia Quadro 600, all subtests pass.

+ * RESOLVED: It is legal. For example, let's say texture 1 is a 2D_ARRAY
+ * texture with 200 layers. It will have TEXTURE_VIEW_MIN_LAYER=0,
+ * TEXTURE_VIEW_NUM_LAYERS=200. Then we create texture 2 from texture 1
using

+ * TEXTURE_VIEW_NUM_LAYERS=100. Then we create texture 3 from texture 2 using
