* This includes:
- Incorrect comparisons
- Missing type annotations where it can't be inferred
- Variable shadowing and bad use
- Unused imports
- asserts for non-None on types
* Passes clean on strict pyright checking except for
`reportMissingParameterType`, `reportUnusedVariable`, and
`reportOptionalMemberAccess` which are all too spammy and low value to be
worth addressing.
* These come from long ago when using PyCharm with not as good type checking and
with renderdoc module stubs that were incomplete so needed help identifying
types.
This test renders a small triangle that casts a shadow from a point light, onto a larger triangle. The test runner then checks that various pixels in the final output are the correct colour.
There is also an arbitrary AS copy in the render loop just to hit more API coverage when manually capturing, but the test runner doesn't check its output.
