From: Marek Olšák <marek.ol...@amd.com>
All drivers convert these to float, so there is no reason to use double.
This makes piglit/arb_viewport_array/viewport-indices fail, because
glDepthRange accepts double and piglit expects glGetDoublei_v(GL_DEPTH_RANGE)
to return the same value, but this patch rounds it to float.
If people are OK with this, we can modify the test to allow some margin of
error to make it pass.
gl_context::ViewportArray: 512 -> 384 bytes
