* Replace generic tonemap curve with a simpler one
This change removes the shoulder parameter which had inconsistent
behaviors. The new curve is simpler and designed to still match
by default the gray point and the contrast of ACES in a bright
surround.
* Fix build
ostream internals are now protected by a lock, which ensures the
internal state stays consistant, however, this won't prevent
multiple threads to have their output ominterfering with each other,
which is no different from the stl behavior.
This fixes#4992
it was incorrect to store bone matrices as quaternions because it is
allowed for these matrices to have a skew component.
We now store the 4x4 matrix -- which is the same amount of data as
before, however we compute the cofactor matrix in the vertex shader when
transforming normals.
fixes#4887
- the hammersley sequence was completely wrong because of a missing
highp precision qualifier
- roughness 0 was also wrong because of divide-by-0
Fixes#4668
- FILAMENT_SKIP_SDL2=ON is used to skip dependencies of sdl2 and sdl2 CMake
- FILAMENT_LINUX_IS_MOBILE is used for Mobile build

__ANDROID__ is always set by the toolchain and less likely to cause
conflicts than ANDROID. This change also removes the -DANDROID flag
we set ourselves in our toolchain CMake files since we don't need
it anymore.
* Use locale-independent string->float conversion
strtof and friends are locale aware and won't parse decimal numbers
with a period ("12.6" for instance) in locales that use another
character for the decimal period ("," in French for instance).
This change introduces a new function called strtof_c that forces
the use of a specific locale (called "C") to make sure we always
parse floats in the desired "C" format ("12.6").
With C++17 we should be able to use std::from_chars but this API
is not implemented in clang for floats at the moment.
* Fix Linux
This changes how we select the "optimized depth vertex shader", but
this shouldn't change the current behavior.
We now select the "optimized depth vertex shader" if and only if the
user code is empty. In that case, we can safely assume we can remove
all the code that's not necessary for the depth, since it is all
controlled by filament.
When calculating the linear depth for VSM, we were using the whole
range between 0 and the far plane, the near plane wasn't taken into
account.
This can be a problem is the light is very far, but it's near plane is
closer to the camera/scene, in this case the depth precision wasn't
used optimally.
Note that we don't hit this problem currently, because the directional
light is constructed such that its origin is at the near plane, and the
spotlights have a fixed near plane (which is a problem and will be
fixed at a later time).
The codebase needs only a few additional standard #includes to compile
against libstdc++ on Linux; presumably those headers are implicitly
included with MSVC's and Clang's standard C++ library, but even if
libstdc++ compatibility is not a goal, it is advisable to have them
included directly.
* mipgen: Linearized PNG bitmaps (such as normal maps) no longer perform gamma transform on read.
* mipgen: Using "-k normals" argument now works for all file types, not just KTX
* Web: Exposed SurfaceOrientation functions getQuatsHalf4() and getQuatsFloat()
When supported and enabled, resolve MSAA using an HDR aware filter,
which improves anti-aliasing quality.
This is only supported with backends that support multi-sampled
framebuffer-fetch. Currently, only Metal on iOS and GLES.
