From the spec: "A declaration must not introduce a name when that
identifier is already in scope with the same end scope as another
instance of that name."
naga doesn't yet check this (gfx-rs/naga#1480) but Chrome/Tint rightly
complains with: error: redefinition of 'main'
* Introduce SamplerBindingType enum and fix bug in validation
This matches the WebGPU spec more closely and also lets us implement the
validation as it's written in the spec[1]. This fixes a bug which
previously prevented the "shadow" example from running in Firefox.
Previously the validation would check whether the filtering was
appropiate even if it was a comparison sampler. This didn't matter when
running the shadow example natively since the example was setting
`filtering: true` in addition to `comparison: true`. But this failed
when running through a browser since there the used WebIDL has the
proper enum representation and eventually resulted in `filtering: false`
being passed to wgpu-core which would then fail validation.[2]

* Fix remaining examples
* Fix deno_webgpu
* Renamed clear_buffer to fill_buffer (keeping up with spec)
* fill_buffer does not require CLEAR_BUFFER feature
* Changed ClearBuffer to FillBuffer for `trace` feature
* Renamed clearBuffer for web backend
* Creation of max compute workgroup size limits
* Implemented for Vulkan and Dx12
* Follow up of gfx-rs/wgpu#1808
* Check if current dispatch operation is under the limit
* Typos and some forgotten fixes
* Port to GLES
* Port to Metal with default limits
* Change Vulkan max_workroup_size_per_dims to pick the min of the reported dimensions

* Added tests for texture zero init
sadly, they are typically passing even if texture zero init isn't doing its job
However, they form nice isolated examples for testing out texture initialization
It could be possible to dirty texture memory prior to ensure zero init did the job
* texture init tracker
* tracking texture init requirements for bind group, transfer and rendertarget
* texture clears for texture init
* queue submit
* write_texture
* Enforce presence of either render target or copy_dst flag
* clear render targets also with using buffer copies
enforce COPY_DST usage now on all textures
* adjust ImageSubresourceRange.layer_range calculation for 3D textures
init_tracker has now a `discard` function to get single data points back to uninitialized
use new standardized partition_point function
* track init state for discarded textures from renderpasses
missing:
* init on the fly if discarded is found within command buffer
* handle discarding only stencil or only depth
* added tests for zero init after discard
* tracking discarded surfaces now in separate struct, piping all inits through utility function
allows to resolve discard/init_action interactions
* Move various memory init code to separate mod
CommandBufferTextureMemoryActions is now fully encapsulated
* implemented discard init fixups for everything but renderpass
* render passes also cause now discard fixups
* fixup_discarded_surfaces takes now an iterator instead of Drain
* Add memory init test for discarding depth targets
* handle divergently discarded depth/stencil target
* comment & clippy fixes
* fix collect_zero_buffer_copies_for_clear_texture yielding block breaking copies
* [pr feedback] minor cleanup in zero_init_texture_after_discard, `use` hygenie
* [pr feedback] fix bug in ImageSubresourceRange range utils
* [pr feedback] fix texture tracker check, bundle transition_texture on init, cleanups
* Implemented drop for InitTrackerDrain
* remove incorrect comment about extents in add_pass_texture_init_actions
* Fix unit test & clippy issues in init_tracker
Currently the configure function reuses the surface texture if it
already exist, and will call Glow::Context::tex_storage_2d to
reconfigure the texture. However doing so on an already configured
texture will cause the browser warning:
WebGL warning: texStorage(Multisample)?: Specified texture is immutable.
and will NOT apply the new configuration such as new dimensions.
