Replace `typedef` with `using` in C++ code.
In the case of `typedef struct SomeName { ... } SomeName;` I removed the
`typedef` altogether, as this is unnecessary in C++. Such cases have been
rewritten to `struct SomeName { ... };`
No functional changes.
This makes it possible to disable all the extensions when forcing
workarounds.
Also it will allow future options to selectively disable each extension
to know which one is buggy.
This makes the GPUContext follow the same naming convention as the rest
of the module.
Also add a static getter for extra bonus style (no need for casts):
- Context::get()
- GLContext::get()
This is part of the Vulkan task T68990.
This commits changes a few things:
- Rename extensions to capabilities (but left the file name untouched).
- Cubemap mip render workaround detection is rewritten using gl
commands to avoid using the GPU API before initialization.
- Put all the capabilities that are only relevant for the GL backend
inside GLContext as static variables.
- Cleanup the names of the limit variables.
- Separate all GL related workaround search inside the GL module.
This is part of the Vulkan backend task T68990.
There is no real change, only making some code re-organisation.
This also make the IndexBuf completely abstract from outside the
GPU module.
After drawing, the batch could be reset and draw again using other
parameters.
Avoid having to track references by setting the batch pointer to NULL after
drawing.
