Checks that:
* TEXEL_SIZE
* IMAGE_COMPATIBILITY_CLASS
* IMAGE_PIXEL_FORMAT
* IMAGE_PIXEL_TYPE
return the values defined for them in Table 3.22 of the OpenGL 4.2
specification depending on the "Image Format" passed.
For unsupported resources, this test checks that the returned value
is equal to the 'unsupported' response defined by the extension
specification.
v2: check for unsupported values, so testing this pnames could be
removed from generic-pnames
Tested on NVIDIA GeForce GTX 950 - NVIDIA 352.55: fails:
* IMAGE_TEXEL_SIZE
From spec:
The size of a texel when the resource when used as an image
texture is returned in <params>. This is the value from the
/Size/ column in Table 3.22. If the resource is not supported
for image textures, or if image textures are not supported, zero
is returned.
NVIDIA proprietary drivers returns 1, 2 or 4, a values not present
on Table 3.22.
* IMAGE_PIXEL_TYPE:
From spec:
The pixel type of the resource when used as an image texture is
returned in <params>. This is the value from the /Pixel type/
column in Table 3.22. If the resource is not supported for image
textures, or if image textures are not supported, NONE is
returned.
NVIDIA proprietary drivers returns in some cases
GL_UNSIGNED_INT_8_8_8_8_REV, that although defined on core spec 4.2,
it is not included on Table 3.22
* IMAGE_PIXEL_FORMAT:
From spec:
The pixel format of the resource when used as an image texture
is returned in <params>. This is the value from the /Pixel
format/ column in Table 3.22. If the resource is not supported
for image textures, or if image textures are not supported, NONE
is returned.
NVIDIA proprietary drivers returns in some cases GL_R11F_G11F_B10F,
that although defined on core spec 4.2, it is not included on Table
3.22
