2021-04-20Various fixes to make `model-viewer` example almost working. (#1801)Yong He
* 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

2021-04-05Fix a bug in the "operator cache" (#1784)Tim Foley
In order to speed up compilation, the semantic checking step uses a cache for overload resolution in the case of an operator being applied to operations of basic scalar types and vectors/matrices thereof. The logic for construct keys for that cache was defensive against the case of, e.g., `vector<int,N>` where the element count `N` of the vector was not a literal value but a generic parameter. For some reason it did not have equivalent safeguards for a case like `vector<T,2>` where the element type was not a basic type, and it would instead assume all vector/matrix types had basic types as their element type. This change fixes the logic to make it properly defensive against this case. Co-authored-by: jsmall-nvidia <jsmall@nvidia.com>
