Until hardware appears (in a gallium driver) that can make use of the
TCS-outputted gl_BoundingBox, we just request that the variable gets
assigned as a regular patch variable.

These are the only platforms that current expose OES_geometry_shader.
Once OpenGL ES 3.1 and OES_geometry_shader are enabled on Gen7, this
extension can be enabled there as well.
Gen6 will never get OpenGL ES 3.1, so it will never get this
extension... even though it has the desktop OpenGL extension. Alas.
NOTE: This causes a failure on Gen8+ platforms in
ES3-CTS.gtf.GL3Tests.texture_storage.texture_storage_texture_targets.
The test only fails because it doesn't know that 0x9009 is a valid
value when the extension exists.

Gen7 can get this extension (and GL_OES_shader_io_blocks) as soon as the
rest of OpenGL ES 3.1 is enabled.

The additional provision of GL_OES_copy_image is that it work for ETC.
However many desktop GPUs don't have native ETC support, so st/mesa does
the decoding by hand. Instead of discarding the compressed data, keep it
around in CPU memory. Use it when performing image copies.

This enables GL_shader_draw_parameters and GL_ARB_indirect_parameters as well
as a properly accelerated implementation of GL_ARB_multi_draw_indirect.
Enabling the feature requires a sufficiently uptodate firmware -- those have
already been released a long time ago, although this does mean that the
feature only works with the amdgpu kernel module, since the radeon module
doesn't have a way to query the firmware version.
