GLES always clamps for 32-bit float buffers, GL doesn't require
it but setting this per API causes virgl to fail some tests.
To fix is properly we'd need to introduce a CAP to expose
this between host/guest.

This was useful for emulating GL 3.2 in virgl on a GLES3 host renderer,
before GL_EXT_depth_clamp introduced the ability for hardware drivers to
expose the feature on GLES. Now that we have that, the desktop-GL-capable
HW that virgl cares about can expose desktop GL even on its GLES renderer
on the host without this emulation. I don't think anyone particularly
cares about hitting higher GL versions on actually-core-GLES hosts with
virgl.

This is required for d3d10+, which has depth_clamp always enabled
regardless of depth_clip (in contrast to OpenGL, where enabling
depth_clamp disables depth_clip). There doesn't seem to be a GL
extension for it, but it will be used for lavapipe to implement
VK_EXT_depth_clip_enable.

The OpenGL ES 2.0 (and later) specifications, section 2.13 (Primitive
Clipping) say the following about point-clipping:
> If the primitive under consideration is a point, then clipping
> discards it if it lies outside the near or far clip plane; otherwise
> it is passed unchanged.
This matches the D3D convention, and we already have a rasterizer-state
bit for it. So let's set that bit when the API is OpenGL ES 2.
We can set this inside the PointSprite-conditional block, because that's
always enabled on GLES 2, and it's undefined to enable this state
without also enabling point_quad_rasterization.

Currently, drivers infer the line rasterization mode from the
multisampling and line_smooth rasterization state. This is always
correct for OpenGL, but is subtly incorrect for DirectX 9, 10 and
Vulkan (when VK_EXT_line_rasterization is supported).
So let's allow front-ends to choose freely between rectangle and
paralellogram rendering.
The reason why there's no added cap for this, is that the implicit
selection that drivers currently do will work just as well (or more
correclty, just as subtly wrong) as before. And there's nothing
reasonable the front-ends can do to get the correct behavior, so
there's really no fall-back code to write either.

That implies that atoms can't specify which flags they consume.
There is exactly one ST_NEW_* flag for each atom. (58 flags in total)
There are macros that combine multiple flags into one for easier use.
All _NEW_* flags are translated into ST_NEW_* flags in st_invalidate_state.
st/mesa doesn't keep the _NEW_* flags after that.
