The non-const getSkybox() method is especially useful to client code
that needs to change the clear color, but does not have direct
access to the Renderer object.
* Minor clean-ups
- fix a couple usage of std::function
- fix a couple usage of std::string
- remove ALIGN_LOOP, which didn't work
- fix a couple explicit/noexcept
- virtual -> override
* Fix spelling typos and other minor clang-tidy
This does not add any build stuff or new sample code yet, it just does
some prep to our C++ codebase:
- Similar to Android, WebAssembly will not be using BlueGL. We were
using a mixture of #if and #ifdef when checking for the existence of
certain GL prototypes, but the latter is what we want in order to
build robustly with any GL headers. (We still perform run-time checks
for extensions, this doesn't change that.)
- Add a trivial ContextManager, does a bit more than Dummy since it
needs to create an actual driver. This doesn't get compiled yet, it
just adds files to the tree.
- WebAssembly does not support mmap, execinfo, or asm volatile.
* Add single-threaded config to Filament.
This adds a tick method to Engine and disables a couple components
in Renderer (FrameSkipper and FrameInfoManager).
This will make it easier to support WebGL, and will allow us to remove
some of the command buffer debugging stuff that we added for Vulkan.
* tick => execute, and other review feedback
* Restore the ASSERT for FFence::wait.
