This release contains a collection of fixes and improvements, including
one new vendor extension. Notably, we have relicensed all files that
become part of the loader, so the loader may be “Apache-2.0 OR MIT” for
downstream license compatibility.

internal MR 1970)

on Windows, so they are treated as a relative path. (internal MR
1975)
- Fix searching for prerequisites in generated CMake config files.
(internal MR 1963)
- Start shipping the OpenXR API layers with the release artifacts.
(internal MR 1975)
- cmake: Debug library uses d suffix on Windows. CMake
OPENXR_DEBUG_POSTFIX variable can be set to something else to
change it. (OpenXR-SDK-Source/#229)

(internal MR 1933)
- hello_xr: Return supported sample count as 1 for GLES, GL and
D3D11. (internal MR 1962)

NativeActivity subclass. (internal MR 1976)
- hello_xr: On Vulkan, explicitly add surface extensions for
mirror window. (OpenXR-SDK-Source/#230, internal MR 1934)
- loader: Relicense all files that become part of the loader, so
the loader may be “Apache-2.0 OR MIT” for downstream license

- loader: Protect against the application overriding loader
symbols. (internal MR 1961)

issue 42, internal MR 171)

interaction profile. (internal MR 1556)

Patch release for the 1.0 series.
This release contains, among other things, a substantial simplification and
cleanup of the loader, which should fix a number of issues and also make it
forward compatible with extensions newer than the loader itself. As a part of
this change, the loader itself now only supports a single `XrInstance` active at
a time per process. If you attempt to create a new instance while an existing
one remains (such as in the case of application code leaking an `XrInstance`
handle), the loader will now return `XR_ERROR_LIMIT_REACHED`.

No API changes, and only minimal consistency changes to the spec/registry.
Mostly an update for tooling, layers, loader, and sample code.
Header version has been bumped to 43, but no symbols that should have actually been in use have changed.

This is the initial migration of source code from the OpenXR Gitlab
repository to the public Github OpenXR-SDK repo. It is a snapshot of
the source tree (i.e. everything under /src on Gitlab), taken at the
Gitlab tag 'SPEC_0.90.0_FREEZE_PENDING_RELEASE', aka commit SHA
5d1ad822c1bc10a3d3bce1f6186b0afd990fe245.
Build breakage is expected at this commit.
