   - layers#275 Allow higher quality filtering
   <https://github.com/immersive-web/layers/issues/275> requested by
   cabanier
   <https://github.com/immersive-web/layers/issues/275#issuecomment-1416998318>

Meta added support
<https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#XR_FB_composition_layer_settings>
 to enhance the quality of composition layers (this includes projection). I
don't remember where we left this but when I turned this on as an
experiment, video layers were visibly improved

add support to layers for different quality settings


   - layers#298 Add option to skip the clearing of textures
   <https://github.com/immersive-web/layers/issues/298> - cabanier

The WebXR layers spec defines
<https://immersive-web.github.io/layers/#opaque-texture> that the textures
that are returned from the binding are always cleared to opaque black. This
feature is hard to implement without incurring GPU overhead especially when
dealing with multiple layers.


   - layers#299 Remove chromaticAberrationCorrection option
   <https://github.com/immersive-web/layers/issues/299> - cabanier

As far as I know, no experience has ever used this feature and it is not
even hooked up in the browser anymore as OpenXR doesn't support it.


   - webxr#1310 Add support for 'palmspace'
   <https://github.com/immersive-web/webxr/issues/1310> - cabanier

OpenXR added support for a palm pose
<https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#XR_EXT_palm_pose>.
This allows an experience to figure out where the user's hand/palm would be
when they use the standard OS controller.


   - webxr#1311 Duplicated controllers behind trusted UIs
   <https://github.com/immersive-web/webxr/issues/1311> - emmanueljl

If an experience doesn't hide its custom controllers when trusted/system
UIs are shown, a duplicate pair of controllers will be displayed. Many
experiences don't handle this properly, even when blur visibility-change is
fired. It was made more apparent with our soft release of system keyboard
support.[1 <https://twitter.com/emmanueljlee/status/1603550385230299136>]
Currently this scenario isn't addressed in the spec, e.g. in the Trusted UI
section <https://www.w3.org/TR/webxr/#trustedenvironment-security>.
