From the ARB_internalformat_query2 specification:
"- SIMULTANEOUS_TEXTURE_AND_DEPTH_TEST: The support for using the resource
both as a source for texture sampling while it is bound as a buffer for
depth test is written to <params>. For example, a depth (or stencil)
texture could be bound simultaneously for texturing while it is bound as
a depth (and/or stencil) buffer without causing a feedback loop, provided
that depth writes are disabled.
- SIMULTANEOUS_TEXTURE_AND_STENCIL_TEST: The support for using the resource
both as a source for texture sampling while it is bound as a buffer for
stencil test is written to <params>. For example, a depth (or stencil)
texture could be bound simultaneously for texturing while it is bound as
a depth (and/or stencil) buffer without causing a feedback loop,
provided that stencil writes are disabled.
- SIMULTANEOUS_TEXTURE_AND_DEPTH_WRITE: The support for using the resource
both as a source for texture sampling while performing depth writes to
the resources is written to <params>. For example, a depth-stencil
texture could be bound simultaneously for stencil texturing while it
is bound as a depth buffer. Feedback loops cannot occur because sampling
a stencil texture only returns the stencil portion, and thus writes to
the depth buffer do not modify the stencil portions.
- SIMULTANEOUS_TEXTURE_AND_STENCIL_WRITE: The support for using the resource
both as a source for texture sampling while performing stencil writes to
the resources is written to <params>. For example, a depth-stencil
texture could be bound simultaneously for depth-texturing while it is
bound as a stencil buffer. Feedback loops cannot occur because sampling
a depth texture only returns the depth portion, and thus writes to
the stencil buffer could not modify the depth portions.
For all of them,
"Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
If the resource or operation is not supported, NONE is returned."
