* Tests that asking for more that GL_MAX_SAMPLES fails.
*
* From the EXT_framebuffer_multisample spec:
*
* "If either <width> or <height> is greater than
* MAX_RENDERBUFFER_SIZE_EXT, or if <samples> is greater than
* MAX_SAMPLES_EXT, then the error INVALID_VALUE is generated."
*
* Skips if ARB_texture_multisample or ARB_internalformat_query are
* supported. ARB_texture_multisample changes the error which should
* be generated; ARB_internalformat_query allows the limit for particular
* internalformats to be >MAX_SAMPLES.
