This can have a dramatic effect on SSAO and needs
to be adjusted based on the scene's scale/units.
The default value used to be about 6cm, and has
been changed to 5mm.
this allows the sidecar buffer to have the same lifetime than the
texture it represents, and therefore participate to the caching of
that texture.

* WIP New tone mapper API
* Implement tone mapper constructors and destructors
* Add new genertic tone mapper
* Make the generic tone mapper available in our sample UIs
* Fix warnings and crashes
* Fix generic tone mapper and graph mappers in the UI
* Add Java APIs for ToneMapper
* Implement copy/move operators for GenericToneMapper
This lets you see highly readable GLSL when transpiling the generated
SPIRV back to GLSL, with the original variable names preserved.
For now this is only useful when using `matinfo`, but it will soon be
useful in `matdbg` too.
The API now allows to create a standalone SkinningBuffer containing
Bones for skinning. This SkinningBuffer can even be very large and
contain bone data for several renderables.
New APIs on RenderableManager allow to switch to skinning buffer mode
and to set the SkinningBuffer (and window into it) to use.
Fixes#3238
* Generalize luminance scaling in color grading
Previously the luminance scaling step was tied to a specific tone
mapping operator, called "EVILS" in the API. This was however
somewhat misleading as EVILS really is a color handling system
that's independent of what we call tone mapping.
This change splits the luminance scaling step from the tone mapping
step, allowing the use of luminance scaling (the LICH part of EVILS)
with any tone mapping operator.
As a result, the operator known as EVILS is currently mapped to the
linear operator and renamed to "RESERVED" until it is replaced by
a proper — configurable — operator.
* Update release notes
* Fix web build
Saturation and vibrance were using the wrong luminance weights,
and this change switches EVILS to HK weighted luminance weights
to give better results.
What was happening is that we were doing two blits at the end of the
frame instead of one, those blits are setup so that they only work
when the destination is the an imported target (it doesn't have to be
this way, but currently that's the only case we should have). Because
of the 2nd blit, the first one's destination would not be the
imported target and it would fail.
The real problem is that we shouldn't be doing two blits, just one
is enough. That was happening because the logic to decide if we
needed the last blit was flawed.
Fixes#4306
Previously we were zero filling the data blob used to store all Vulkan
handles. This occured in VulkanDriver::alloc_handle().
There were several places that depended on the zero fill. These
have now been fixed up so that the handle can be constructed in a
more natural way.
Also: remove the OPENGL specific constant from HandleAllocator. This
breaks in non-CMake build systems (e.g. Bazel) that do not provide the
constant at a global level.
We now have:
allocate<> which just allocates the handle's memory
construct<> which constructs the handle allocated with allocate<>
allocateAndConstruct<> which allocates AND constructs the handle
destroyAndConstruct<> which destroys and constructs a handle in place
Normally you'd use allocate/construct but with synchronous calls, it
might be necessary to have an initialized handle immediately.
Previously, Metal was never performing any texture conversions during upload. For example, `iblprefilter` loads `FLOAT` image data into the `R11F_G11_B10F` texture format. This PR fixes the issue, refactors the upload pipeline, and adds a new backend test for coverage.
Image loading errors are handled more gracefully by showing a
background color.
Added UI to set the background color.
Replaced fragment discards with solid background color.
* Add new sample app: image_viewer
This app shows how to load and visualize images. It's also useful to work
on color grading and other post-processing effects by just loading an HDR
or EXR image as a reference.
This change also adds a new exposure setting to the color grading LUT.
* Fix comments and build
* Fix Metal
* Use high precision for the UV coordinates
* Fix refactoring issue
* Add support for KHR_materials_volume
* Add ubershader support for KHR_materials_volume
* Update readmes
* User highp on anything that affects UVs
* Add missing precision qualifiers
* Fix transmission
