This fixes `GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE` caused by the
following spec clause being violated:
```
The value of RENDERBUFFER_SAMPLES [must be] the same for all
attached renderbuffers and, if the attached images are a mix of
renderbuffers and textures, the value of RENDERBUFFER_SAMPLES
is zero.
```
Tested on Chrome with Triangle and Helmet demos (after enabling MSAA).
Also tried running the automation suite in a debug build on macOS.
Fixes#3128.
This adds setMinMaxLevels to the DriverAPI and calls it from
PostProcessManager and the new unit test. The allows us to be compliant
to the OpenGL specification. The new unit test now looks much better on
Intel GPUs. Chrome still gives an INVALID_OPERATION.
Unfortunately the actual bloom effect still has issues on my Intel GPU,
even though the test passes. So, we need to keep the ping-pong
implementation both for Chrome and for Intel.
I noticed that our slerp function sometimes produces a jolt in
animation, but only when the time delta is very small, and only when the
two operands have completely opposing signs.
For example, let's say you are slerping from <0.76, 0.39, 0.51, 0.19>
to <-0.72, -0.45, -0.49, -0.17>.
These quats are actually quite near to each other because the total
negation of the second quat is similar to the first quat.
We were already doing the short path check in the proper slerp path, but
not when falling back to lerp due to a small angle.
MaterialGenerator selects a custom blend mode for transmissive models,
therefore the AssetLoader should look at the material's blend mode when
it sets up properties, not the one requested by the glTF file.
Fixes#3444.
Previously this test was actually finding a ReadPixels failure on Intel
GPU's, rather than a failure of feedback loop behavior. This was due to
the fact that it was calling ReadPixels on a non-zero miplevel, which
seems to be unsupported on Intel GPU's.
The test now follows the downsample phase with an upsample phase, just
like the real bloom effect. This allows us to issue ReadPixels on the
base level, thus making the test more targetted to rendering feedback
loops.

Recall that we now use shared_ptr to simplify lifetime management of
cgltf source data (#3413).
Before this commit, we were only using shared_ptr to retain the source
data during buffer uploads. After this commit, we are using it to retain
source data during texture decoding.
Fixes#3428.
Second attempt after abandoning #3451.
Feedback loops do not work with Chrome or Intel GPU's, so we now have an
optional ping-pong implementation of Bloom.
Issue #2338.
This fixes "illegal hardware instruction" seen on my MacBook, which
is the same as #1839, but triggered only in a test environment where
the main thread is the same as the driver thread, and filament is built
with HAS_THREADING enabled.
* Add swap() methods to Allocator.h
This allows StructureOfArraysBase's move constructor to compile.
Removed an apparent workaround in SingleInstanceComponentManager.
* swap can be noexcept
* Add swap() methods to Allocator.h
This allows StructureOfArraysBase's move constructor to compile.

Fix a possible out-of-bound access when reading the x-planes array.
Also account for the fact that the loops filling the froxels assume
stl-like iterators (1-past the end on the right), while the indices
themselves were right-inclusive.
fixes#3142
I tested this by viewing CesiumMan with our `gltf_instances` sample app.
There is now a need for some general refactoring in gltfio. I feel that
the high-level objects have become too tightly coupled to each other.
Fixes#3137.
Only items older than a certain value were purged from the cache,
this allowed the cache to grow unbounded before this age limit was
reached.
We now purge the cache at each frame if it's above the size threshold.
Fixes#3381
don't use slog from a static variable, because it might not have been
constructed yet, due to static initialized order.
For some reason, this happens on aarch64 macs, but this was actually
a real problem.
By default, the demo now reflects the camera instead of the renderable.
However this can be changed via the command line. Users can now change
the backend too.
- add darwin-aarch64 support to bluegl
- remove all aarch64 conditions in our cmakefiles, the architecture
is better handled in the source files (to allow fat binaries later)
When we removed the old "ghetto bloom" demo, we ceased to have any
samples demonstrating the RenderTarget API. This demo is a fairly simple
demonstration of planar reflection.
