Add Renderer::skipFrame() which should be called when intentionally
skipping frames, for instance because the screen content hasn't changed,
allowing Filament to performance needed periodic tasks, such as
cache garbage collection and callback dispatches.
We also improve the ResourceAllocator cache eviction policy:
- the cache is aggressively purged when skipping a frame
- we aggressively evict entries older than 3 frames
The default Config is now set to a more agressive setting.
The ResourceAllocator used to be global and owned by the Engine, this
was causing some issues when using several Renderers because each
one could cause the eviction of cache data for another.
We now have a ResourceAllocator per Renderer, which makes more sense
because most resources are allocated by the FrameGraph.
We also introduce a ResourceAllocatorDisposer class, which is used
for checking in and out a texture from the cache, and destroy the
texture when it's checked-out. That objet is still global.
* don't crash if we don't have a Camera set on View
- also add a method to query if a camera was set
* Update android/filament-android/src/main/java/com/google/android/filament/View.java

- dynamic (default) no restriction apply
- static bounds: bounds and world transform can't be changed
- static: additionaly morphing/skinning and vertex/index buffers are
immutable.
This will allow some optimizations in the future. Currently, we just
store the type but don't do anything with it.
32 sample may be more suited to 2x upsampling, it gives 8 samples per
high-res pixel (instead of 4). This is also what FSR 2.0 is using,
which is useful for comparing.
* Bokeh aspect ratio
new DoF option to set the bokeh aspect ratio, this can be used to
simulate anamorphic lenses

* TAA improvements
- fix variance + AABB history clipping (we were computing the union
of both AABB instead of the intersection).
- added a setting for the variance parameter
- added a setting for the jitter pattern
- improved some default values
- fixed a few comments
- smaller code tweaks to facilitate future improvements
Material constants (a.k.a: specialization constants) can only be set
during Material creation through Material::Builder.
This change somewhat relaxes that limitation by allowing constants to
be set at runtime on Material directly.
Currently this new API is still private and only supported on FMaterial.
This feature works by invalidating the HwProgram cache of the concerned
Material, causing a shader recompile per variant; so this API is costly
and should be used only for debugging or during app/game configuration.
The TAA material is modified to use constants instead of #defines for
various settings and those are exposed in TaaOptions as well is in
ViewerGui. So with this change all aspects of the TAA material can
be changed at runtime.
- deprecate blit(), renamed to blitDEPRECATED. It's only used in one
place in copyFrame() now. We can't void it because we don't have
access to the texture from the RenderTarget.
- add a new blit() api that works with textures instead of render
targets.
- add a new resolve() api that works with textures instead of render
targets. doesn't support scaling.
- always use a shader when scaling in the framegraph
(there was only one place where we used blit)
- use the new blit() for:
- for mipmap generation on vk (fixme)
- copying the depth buffer to avoid ssao feedback loop
- use the new resolve() for:
- manually resolving MSAA color/depth
- Simplify the resolve APIs on the filament side
- implement generateMipmaps for the vulkan backend
simplify MetalBlitter
- remove metal blit workarounds
- don't issue a blit from a renderpass, this only affect Renderer::copyFrame
- We only handle a single texture now (instead of color+depth), so we
can simplify the code a lot.
Didn't touch the "slowpath" much, but it now assumes it blits color or
depth, not both.
