* the actual resolutions that would be used for storing image array
* components for the resource. For compressed internal formats, the
* resolutions returned specify the component resolution of an
* uncompressed internal format that produces an image of roughly the
* same quality as the compressed algorithm. For textures this query
* will return the same information as querying
* GetTexLevelParameter{if}v for TEXTURE_*_SIZE would return. If the
* internal format is unsupported, or if a particular component is not
* present in the format, 0 is written to <params>."
*
* So try_textures_size check if it is 0 when not supported, and that
* the returned value is the same that the one returned by
