*	Share graphics API layer between tests/examples (#603)	Tim Foley	2018-06-28
\| \| \| \| \| \| \| \| \|	The `render-test` project has an in-progress graphics API abstraction layer, and it makes sense to share this code with our examples rather than write a bunch of redundant code between examples and tests. Most of this change is just moving files from `tools/render-test/` to a new library project at `tools/slang-graphics/`. The most complicated code change there is renaming from `render_test` to `slang_graphics`. The existing `hello` example was ported to use the graphics API layer instead of raw D3D11 API calls. It is still hard-coded to use the D3D11 back-end and the `SLANG_DXBC` target, so more work is needed if we want to actually support multiple APIs in the examples. I also went ahead and implemented an extremely rudimentary set of APIs to abstract over the Windows platform calls that were being made in the example, so that we could potentially run that same example on other platforms. I did not* port `render-test` to use those APIs, and I also did not implement them for anything but Windows (my assumption is that for most other platforms we would just use SDL2, and require people to ensure it is installed to their machine before building Slang examples).
*	Feature/dx12 (#469)	jsmall-nvidia	2018-04-02
	* Fix signed/unsigned comparison warning. * Split out d3d functions that will work across dx11 and 12. * Improve slang-test/README.md around command line options. * Make Guid comparison honor alignment for comparisons, such that mechanism work on architectures that can only do aligned accesses. * Initial setup of D3D12 Renderer, with presentFrame and clearFrame. * More support for D3D12 * Added FreeList * Added D3D12CircularResourceHeap * First attempt at createBuffer * First pass at map/unmap. * First pass binding vertex/constant buffers, and setting up InputLayout. Note that memory is not kept in scope on binding yet. * First pass of D3DDescriptorHeap * Small tidy up in render-d3d11. Added D3DDescriptorHeap to project. * First pass at D3D12 bind state. * Fix typos in D3D12Resource * Tidy up Dx11 render binding a little to match more with Dx12 style. * First pass at Dx12 BindingState * Handling of the command list d3d12. Support for submitGpuWork and waitForGpu. * First attempt at Dx12 capture of backbuffer to file. * First attempt at D3D12 binding for graphics. * D3D12 setup viewport etc - does now render triangle in render0.hlsl. * First pass at support for compute on D3D12Renderer * Use spaces over tabs in D3DUtil * Tabs to spaces in D3D12DescriptorHeap * Convert tab->spaces on render-d3d12.cpp
