* Refactor VulkanContext/Driver initialization
Move the initialization of VulkanContext fields to the class
itself. This will clean up how the various extension support
flags are deteremined.
Also disable debugUtils extension for Mesa driver (#6192).
* Re-land #1 "[vulkan] Refactor vkEnumerate methods (#6423)"
This reverts commit 6f7d203adb.
The above commit (6f7d20) is the revert of #6423. Commit
6f7d20 is PR #6425.
"[vulkan] Refactor vkEnumerate methods (#6423)" failed [here] due to
a missing function attribute (VKAPI_ATTR in bluevk) for ARM64
compilers.
[here]: https://github.com/google/filament/actions/runs/3841550984
At least some adreno compilers don't like returning an element of a
UBO array that is a structure in the vertex shader.
To work this around we have to copy the each of the structure fields.
Fixes#6355
Vulkan and Metal should be handled exactly the same within filament,
when it comes to texture-space and clip-space because filament
always transforms vulkan's clip-space to gl's/metal's).
Our shadow code took different paths, both equivalent though, but it's
confusing.
The race coud lead to user after free and crashes.
We now keep a list of acquired streams with pending images on the
main thread, and use that to update the streams synchronously in
beginFrame. We can then enqueue a command for the driver thread that
will look for that stream in the active list of textures with stream
attached. Race avoided.
The previous code used the later list from both threads.
When more than one view was used, only the first view was cleared with
the ClearOption. This was actually intended when the views are rendering
into the swapchain (e.g. post process disabled), but that's incorrect
when the views render into intermediate buffers.
The clear flags are now associated with the actual rendertarget.
* Add new outputColorSpace() API to ColorGrading
This allows the application to select the desired output color space.
The default is set to Rec709-sRGB-D65 ("sRGB") but can be changed to
Rec709-Linear-D65.
Currently only the transfer function is taken into account and must
be either sRGB or Linear. Future updates will add support for
different gamuts and white points.
* Update release notes
