In Direct3D, a stream-output geometry shader can be created from a
vertex shader bytecode. We generate a pass-through geometry shader in
this case. Pass-through geometry shaders are helpful because they can
easily split outputs when rasterization is disabed. We could also add
another codepath in order to avoid geometry shaders when possible.

from feature level checks.

In D3D10+ all clip distances declared in a shader are always enabled.
In other words, enablement of clip distances is a property of a shader.

We never supported, and we should never need to support more than 8 user
clip planes in wined3d.
OpenGL drivers do not expose more than 8 clip distances. Similarly,
other APIs, D3D10, D3D11 and D3D12 provide exactly 8 clip distances.

This is a workaround for a bug in Mesa GLSL linker. The bug is triggered
by GLSL generated for SM3 shaders when shader inputs are not read and
interface blocks are used for shader inputs/outputs (core profile code
path).
Declarations for unused shader inputs are not generated for pixel
shaders. We still declare shader outputs in the previous shader stage,
but it's allowed by the GLSL 1.50 spec:
"Only output variables that are read by the subsequent pipeline stage
need to be written; it is allowed to have superfluous declarations of
output variables."
The table in section 4.3.4 (Input Variables) of the GLSL 4.20 spec even
more explicitly allows shader output variables with no matching input
variables declared in the consuming shader.
