[Mesa-dev] [PATCH 00/15] Add ARB_viewport_array extension

[Courtney Goeltzenleuchter]

This series starts by updating the driver interface for
scissor, viewport and DepthRange. This includes removing
unused arguments from the Scissor, Viewport and DepthRange.
I kept the index argument, although it is not used, it may
be useful to the dri driver to know which array element
is being updated.

I added things incrementally, each having no effect
on piglit. I tested the full series against the arb_viewport_array
piglit tests submitted by LunarG and a stubbed version of the
i965 driver that enables ARB_viewport_array. I've not
included that stub in this series.

I modeled the indexed Get functions off GL_COLOR_WRITEMASK.

Since the removal of x, y, w, h touches the same files as
references to gl_context.Viewport it seemed just as easy to
convert those references to the array reference with index 0.
Should the driver add ARB_viewport_array support they would
simply put the right index value in place of 0.
