Stephen White e2f35ba8e0 GLSL: clean up GLSL output whitespace generation.
More line() and less std::endl.
More automated indents and less manual spacing.
Put a single newline after every struct and function declaration.

Note that this does touch every test result, but only affects whitespace.

Stephen White b1d2b84f7d GLSL: fix clip space mismatch in gl_Position.
OpenGL clips against [-w, w], while WebGPU uses [0, w]. The fix is to
modify gl_Position.z on output to match GLSL semantics. (This is the
same code used by SPIRV-Cross under the fixup_clipspace option.)

James Price 1bf5af25ad reader/wgsl: Allow identifiers to start with an underscore
Try to lex identifiers before punctuation, and backtrack if we only
see a single underscore or something that starts with two underscores.

Rename the modf and frexp return types to start with two underscores.
