2019-03-21	Hotfix/dx12 tests use hardware (#920)	jsmall-nvidia
	* Disable Dx12 half tests. The half-calc test runs, but is not actually doing any half maths. If the code is changed such that it is, the device fails when the shader is used. This can be seen by looking at dxil-asm. * Fix using software driver for dx12 even when hardware is requested. * * Refactor Dx12 _createAdapter such that it doesn't have side effects and stores desc information * Disable half on dx12 software renderer because it crashes * * Disable erroneous warnings from dx12 * Test for adapter creation * Identify warp specifically * Structured buffer test now works on dx12. * Fix intemittent crash on dx12. Due to if a resource was initialized with data, the actual resource constructed might be larger, for alignment issues. This led to a memcpy potentially copying from after the allocated source data and therefore a crash. Now only copies the non aligned amount of data. * * Rename the test to use - style * Disable TextureCube lookup in tests, as does not produce the correct result in dx12 (will fix in future PR) * Updated hlsl.meta.slang.h that has rcp for glsl.
2019-03-18	First pass support for half on vk (#912)	jsmall-nvidia
	* Look at getting half to work on vk. * Alter half test so can always produce consistent test results. * First pass working half on vk. * Improve comments for vulkan extensions around half. * Upgraded vulkan headers to v1.1.103 https://github.com/KhronosGroup/Vulkan-Headers * * Add getFeatures on Render interface * Vulkan renderer determines at startup if it can support half * Parse render-features on render-test * Small changes to half-calc.slang test. * Structured buffer half access works as expected for Vk, but isn't for dx12, so disable for now. * Require the half feature for renderers for the half-structured-buffer.slang test. * * Added ToolReturnCode to be more rigerous about how a return code is passed back from a tool * Added support for a tool being able to pass back an 'ignored' result. * Used enum codes to indicate meanings * Made spawnAndWait return a ToolReturnCode * Ignore tests that don't have required render-feature * Fix macro line continuation usage. * Check dx12 has half support. * Checking for half on dx12 - if CheckFeatureSupport fails, don't fail renderer initialization. * Fix typo.
