HIDAPI's source code licensing says this:
```
HIDAPI can be used under one of three licenses.
1. The GNU General Public License, version 3.0, in LICENSE-gpl3.txt
2. A BSD-Style License, in LICENSE-bsd.txt.
3. The more liberal original HIDAPI license. LICENSE-orig.txt
The license chosen is at the discretion of the user of HIDAPI. For example:
1. An author of GPL software would likely use HIDAPI under the terms of the
GPL.
2. An author of commercial closed-source software would likely use HIDAPI
under the terms of the BSD-style license or the original HIDAPI license.
```
Since the original license in LICENSE-orig.txt is basically only clause 3 of
the zlib license (do not remove this notice from the source code), it makes
sense to switch to it, since it adds no new requirements to the user.
(Plus, it's extremely short and direct, which is always nice.)
The entire license:
```
HIDAPI - Multi-Platform library for
communication with HID devices.
Copyright 2009, Alan Ott, Signal 11 Software.
All Rights Reserved.
This software may be used by anyone for any reason so
long as the copyright notice in the source files
remains intact.
```
Fixes#9786.
Added SDL_Vulkan_DestroySurface, its documentation and corresponding platform specific implementations. Fixed some header inclusion orders to improve consistency between platforms. Added TODOs regarding MetalView creation and destruction which will benefit from the new functionality.
This isn't C++ code, so there's no need to append global symbols with two
colons. It looks ugly.
I _did_ leave them for actual C++ things in WinRT-specific comments and other
places, like a reference to a Perl class thing.
Also, even though it's not valid C, it's a useful expression to say
`StructType::SpecificField`, so I left those alone, too.
This extends the display scaling mode to be global and work in terms of pixels everywhere, with the content scale value set on displays. The per-window property had some issues, and has been removed in favor of retaining only the global hint that changes all coordinates to pixel values, sets the content scale on the displays, and generally makes the Wayland backend behave similarly to Win32 or X11.
Some additional work was needed to fix cases where displays can appear to overlap, since Wayland desktops are always described in logical coordinates, and attempting to adjust the display positions so that they don't overlap can get very ugly in all but the simplest cases, as large gaps between displays can result.
