There's one failure still, where a deleted program should still be
considered to be a program until it's unbound. However, I recently
made it so that we unbind at delete time, and we may need to partially
back that change out.

There's one failure still, where a deleted program should still be
considered to be a program until it's unbound. However, I recently
made it so that we unbind at delete time, and we may need to partially
back that change out.
We keep bindings that shadow what's mapped in the GL state currently,
and so we need to remove the objects from our binding points when they
get implicitly removed from the GL binding points during object deletion.
On a GLES or compatibility underlying GL context, we were fine because
an underlying renderbuffer object would just get re-created, and
nothing too bad happened because we aren't tracking the currently
bound renderbuffer at the DOM level. However, on a desktop GL core
context, binding non-genned or deleted names is an error.
Fixes a crash in object-deletion-behavior.html.
To do this, we need to keep a map of GL names (encapsulated as
WebGLFramebufferId) to WebGLFramebuffer objects so that we can return
the right type.
Fixes#12852
The VertexAttrib[234]fv compare to the same size as in their function
name. This wasn't noticed becacuse this function isn't connected from
the .webidl yet.
This commit introduces the `WebGLValidator` trait, and uses it for multiple
validations in the texture-related WebGL code, to move that logic out of the
already bloated `webglrenderingcontext.rs` file.
It also creates a type-safe wrapper for some WebGL types, removing all the
`unreachable!`s there, and introduces a macro for generating them conveniently.
This partially addresses #10693, pending refactor more code to use this
infrastructure, and (possibly?) introducing an `AsGLError` trait for the errors
to make the error handling happen in `WebGLContext`.

Implement copyTexImage2D and copyTexSubImage2D for WebGLRenderingContext. Feedback would be appreciated. I did my best to follow the [spec](https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8). Please let me know if I missed anything. I couldn't find tests for this. Let me know if I should create one. I'm more than happy to do so. As always any feedback, comments,or critiques are very welcome 😄
Part of #10209

It's a pointless abstraction that propagates the obsolete chan terminology,
swaps the order in which the sender and receiver are returned, and hides a
source of panics.
webgl: Implement the pending texImage2D overload, and add more validation
This is a large-ish refactor of the Texture2D code, but it should be
easier to read and of course more correct.
I tried to annotate every error condition with a spec paragraph.
I made just a reftest to ensure this works as intended, since I expect #10373 to land pretty soon.

It's broken for uniform arrays, since uniform.id() stops being the index
then.
We need to add a more complex integration with angle for this to ever
be correct.
Unfortunately the ANGLE part that we should touch is C++, and it has
destructors, so we need to hook destructors there, and I can't do it
right now.
