 107  * This tests min_levels, num_levels, immutable_levels  and imutable_format.
 108  * note: see params test for more min/num  level query testing
 109  *
 110  * In OpenGL Core 4.3 spec see section 8.18:
 111  *    "The minlevel and minlayer parameters are relative to the view of
 112  *    origtexture. If numlayers or numlevels extend beyond origtexture, they
 113  *    are clamped to the maximum extent of the original texture.
 114  *    If the command is successful, the texture parameters in <texture> are
 115  *     updated as follows:
 116  *       - TEXTURE_IMMUTABLE_FORMAT is set to TRUE.
 117  *
 118  *       - TEXTURE_IMMUTABLE_LEVELS is set to the value of
 119  *         TEXTURE_IMMUTABLE_LEVELS from the original texture.
 120  *
 121  *       - TEXTURE_VIEW_MIN_LEVEL is set to <minlevel> plus the value of
 122  *         TEXTURE_VIEW_MIN_LEVEL from the original texture.
 123  *
 124  *       - TEXTURE_VIEW_NUM_LEVELS is set to the lesser of numlevels and the

 126  * In the ARB_texture_view extension registry spec see this for chained views:
 127  *   "(3) Is it possible to create a texture view using an original texture
 128  *   which is itself a view? And if so, how are the level/layer values
 129  *   interpreted?
 130  *
 131  *   RESOLVED: It is legal. For example, let's say texture 1 is a 2D_ARRAY
 132  *   texture with 200 layers. It will have TEXTURE_VIEW_MIN_LAYER=0,
 133  *   TEXTURE_VIEW_NUM_LAYERS=200. Then we create texture 2 from texture 1 using
 134  *   <minlayer>=100, <numlayers>=100. It will have TEXTURE_VIEW_MIN_LAYER=100,
 135  *   TEXTURE_VIEW_NUM_LAYERS=100. Then we create texture 3 from texture 2 using
 136  *   <minlayer>=50, <numlayers>=50. It will have TEXTURE_VIEW_MIN_LAYER=150,
 137  *   TEXTURE_VIEW_NUM_LAYERS=50."
