* Added instancing support to Vulkan, drawInstanced() test image is upside-down
* Fixed inverted drawInstanced() test output by changing Vulkan viewport convention
* Replaced vkCmdDraw with vkCmdDrawIndexed in all non-indirect indexed draws, drawIndexedIndirect test now working for Vulkan
* Moved index and vertex buffer binding into setIndexBuffer and setVertexBuffers; Defaulted countBuffer to nullptr and countOffset to 0 and added a check for non-null countBuffer to drawIndirect and drawIndexedIndirect in Vulkan; All Vulkan draw tests working (but D3D12 tests broken)
* Added support for drawInstanced and drawIndexedInstanced to D3D11 and added tests for both, however D3D11 tests are currently disabled due to readTextureResource assuming a fixed pixel size (among other possible problems); Fixed issues causing D3D12 tests to fail after major back-end fixes to get Vulkan up and running
* Removed testing function for dumping images and some other commented out code
* Removed some commented out code
* Fix initializer list causing builds to fail (attempt 1)
* Removed initializer list for VertexStreamDesc in createInputLayout() and fill in struct fields normally (build fix attempt 2)
* Removed default values from VertexStreamDesc and changed all initializer lists to reflect this change
* Moved applyBinding before setVertexBuffer in RenderTestApp::renderFrame() to ensure the pipeline has already been bound before vertex buffers are
* Changed D3D11's readTextureResource to calculate pixel size using format-specific size information; Removed wrapper around D3D11 instanced and indexed instanced draw tests

* Format list updated with additional formats supported by both D3D and Vulkan; D3DUtil::getMapFormat() and VkUtil::getVkFormat() updated to include additional formats; GFX_FORMAT() updated with all additional formats (BC compression unfinished)
* Finished updating GFX_FORMAT with newly added formats and sizes; Pixel size is now tracked using the FormatPixelSize struct containing the values for bytes per block and pixels per block to accomodate BC formats; Updated gfxGetFormatSize and associated sub-calls to return FormatPixelSize instead of uint8_t; Most calls to gfxGetFormatSize() updated to reflect changes, a couple calls still unupdated
* Changes to accommodate new formats finished, debugging slang-literal unit test
* First format unit test working
* One test added for BC1Unorm and RGBA8Unorm_SRGB, both passing
* Refactored format testing code to merge BC1Unorm and RGBA8Unorm SRGB into a single file
* All unit tests added for BC and Srgb formats
* Most tests added and working; Added five additional formats (still need tests) and made the appropriate changes to support these; createTextureView() modified for D3D11, D3D12, and Vulkan to take into account the format specified in the texture view desc when the texture's format is typeless
* Format enums renamed to more closely match their D3D counterparts; Added a universal float and uint buffer and buffer view for use across all Format tests
* Remaining tests added; D3D12 tests pass, but Vulkan crashes in BC1_UNORM and D3D11 spits out a bunch of D3D11 Errors (but supposedly passes)
* re-run premake
* Added Sint versions of test shaders; Vulkan and D3D11 tests also pass
* Size struct for format unit tests no longer use initializer lists
* Fixed a Size struct missed in the previous pass
* Fixed minor bugs causing tests to fail
* Added documentation detailing all currently unsupported formats
* Skip tests causing unsupported format warnings due to swiftshader
* updated several test using old Format enum names
* Revert change to compareComputeResult() that was added for debugging purposes
* DEBUGGING: Added prints to identify which formats are failing on CI
* Reverted attempted debugging changes; Fixed texture2d-gather.hlsl to use updated Format enums
* Fixed incorrect array sizes in d3d11 _initSrvDesc()
* Commented out further tests that produce unexpected results when tested for Vulkan with swiftshader
* Revert "Merge branch 'expanded-format-support' of https://github.com/lucy96chen/slang into expanded-format-support"
This reverts commit 20008f0d3ecc3b1405ecac8c138edaa3cd37ed6b, reversing
changes made to 6081e95827315fee50e18409394d5abd62fac787.
* Added a fuzzy comparison function for use with floats
* submodule update
* Revert messed up changes caused by previous revert after automatically merging on github

* Fixing `PseudoPtr` legalization and `gfx` lifetime issues.
* Fixing `model-viewer` example.
This change contains various fixes to bring `model-viewer` example to fully functional. These fixes include:
1. Add `spReflectionTypeLayout_getSubObjectRangeSpaceOffset` function to return the space index for a sub object referenced through a `ParameterBlock` binding.
2. Make sure `D3D12Device` specifies column major matrix order creating a Slang session.
3. Fix `platform::Window::close()` and `platform::Application::quit()`.
4. Fix memory leak during `model-viewer''s model loading.
5. Fix command buffer recording in `model-viewer`.
With these changes, model viewer can now produce an image with a gray cube. The lighting is still incorrect becuase the `gfx` shader object implementation still does not handle "pending layout" resulting from global existential parameters.
* Fix d3d12 root signature creation.
* Use row-major matrix layout in model-viewer

* Reimplement Vulkan shader objects.
This change reimplements Vulkan shader objects in the `gfx` layer so that it is no longer layered on top of the `DescriptorSet` abstraction. Since this is the last implementation that uses `DescriptorSet`, the change also removes all `DescriptorSet` related API from public `gfx` interface.
The Vulkan implementation now passes all test cases, but it still have two issues:
1. The PushConstant setting is not correct, this is because we don't seem to be able to get correct reflection data about the size of push constants for an entry-point.
2. The `shader-toy` example can't run on Vulkan, because it currently sets nullptr to `Texture` bindings, and this change doesn't properly handle setting resource to null in `ShaderObject`s yet. If we can use the `nullDescriptor` feature on vulkan, this implementation will be simple. However we still want to decide whether we want to use a Vulkan 1.2 feature for this.
* Fix up

* Change representation of initial data for textures
Before this change, initial data for a texture has been provided with the `ITextureResource::Data` type, where a call to `IDevice::createTexture()` would take zero or one `Data` and, if present, use it to initialize all the subresources of a texture.
The organization of `Data` was not actually quite how its own documentation comment described it (the implementations didn't agree with the comment), and while it aggressively factored out redundancies (e.g., only storing the stride for each mip level once, instead of once per subresource for large arrays), the result was that setting up a `Data` correcty was a bit confusing.
This change makes the initial data for a texture using a `SubresourceData` type that is almost identical to what D3D11 uses, so that developers are more likely to be comfortable filling it in. All of the existing implementations were easily adapted to use the new type, so it seems like a net win.
Note: Both Vulkan and D3D11 do away with the idea of initializing a texture with data as part of allocating it, and we might eventually want to do the same given the complexity that this system entails. The main reason to preserve this detail is for better compatibility with D3D11, where immutable textures/buffers need to have their data specified at creation time. It seems good to preserve the ability to have immutable resources on target APIs where this distinction could affect performance (e.g., immutable resources do not need state/transition tracking on APIs like D3D11).
