Antonio Abbatangelo 080022833d nv2a: Cache shaders to disk 2022-09-10 12:52:51 -07:00
Erik Abair 8d274e5f9a nv2a: Match inv_w qualifier to attribute qualifier 
Calculates both interpolated and flat shaded inv_w so that the appropriate
value may be used when undoing the perspective divide in the pixel shader.

Erik Abair ae1a140ecb nv2a: Fix missing flat qualifier for inv_w param 
`vtx_inv_w` should also be flat, since interpolating it causes incorrect values
for the flat shaded colors.

Fixes #1179

Erik Abair 6f878ede01 nv2a: Do not force oFog to 1.0 
This code was added ~7 years ago in
[this commit](97be3f5986)

From what I can see from the [HW test results](https://github.com/abaire/nxdk_pgraph_tests_golden_results/wiki/Results-Fog_coord_vec4)
the behavior on nv2a is more subtle than the cited `NV_vertex_program`
documentation.

In practice the register more or less retains its value until it is explicitly
modified.[The test](4cff2b2ebe/src/tests/fog_tests.cpp (L432))
renders something with an explicitly set oFog.x, then renders again with a
shader that does not modify oFog.x but references it in the pixel shader. The
value carries over rather than being forced to 1.0.

Interestingly, this test is apparently not hermetic; running the other
vec4_coord test (that explictly set various components of oFog) lead to unusual
behavior where the fogging effect is not uniform across all vertices, despite
never being set. Even more interestingly, re-running the test once it's in this
state will often produce variations as to which vertices are apparently using
a stale/incorrect fog value.
