check if the correct glUniform* overload was used to update the current variable (if this is at all possible)

A number of features have device-specific caps that can only be known through querying the GL.

These capabilities should be queried and stored in a struct in the context at initialization time for us to use later for validation.

so newer functions can be tested

I suggest a 4.6 compat profile header with ARB_bindless_texture (debug mode of course)

https://gen.glad.sh/#generator=c&api=gl%3D4.6&profile=gl%3Dcompatibility%2Cgles1%3Dcommon&extensions=GL_ARB_bindless_texture&options=DEBUG

Suggestions for ubiquitous extensions that are widely used would be helpful.

A way to "soft deprecate" old-but-not-ancient GL functionality. I'm open to suggestions as well.

• Warn if non-DSA functions are used
• Warn if non-storage (TextureStorage, BufferStorage) functions are used
• Warn if VertexAttribPointer is used (prefer VertexAttribFormat, VertexArrayVertexBuffer, etc.)
• Warn if ActiveTexture is used (prefer BindTextureUnit)

Debatably:

• Warn if resource binding indices are set via uniform rather than setting it in the shader with binding = #
• Warn if uniforms are used at all (prefer uniform buffers)
• When drawing, warn if a texture object is bound to a texture binding, but no sampler object is (avoid using the built-in texture sampler state)

This is somewhat related to #1.

We should probably add a toggle (or by default) to discourage the use of legacy api functions (think fixed-function or deprecated functionality that has better alternatives in the gl version the context was created with).
