Queries the "panel orientation" property on the connector and reports it in degrees of clockwise rotation via the 'SDL.display.KMSDRM.panel_orientation' display property.
This is provided by the kernel as a hint to userspace applications, and the application itself is ultimately responsible for any required coordinate transformations needed to conform to the requested orientation.
- Adds support for modal windows to Win32, Mac, and Haiku, and enhances functionality on Wayland and X11, which previous set only the parent window, but not the modal state.
- Windows can be declared modal at creation time, and the modal state can be toggled at any time via SDL_SetWindowModalFor() (tested with UE5 through sdl2-compat).
- Allows dynamic unparenting/reparenting of windows.
- Includes a modal window test.
The idea is that if you have a `typedef Uint32 MyFlags` that has a bunch of
defines that are meant to be bitflags, you can pack them into the same wiki
page automatically.
This only works with `typedef`s that are _not_ struct/union/enums, and it
only pulls in `#define` lines that immediately follow the typedef line.
Even a blank line or a comment will signal to stop including lines for
this page!
This is just stuff I noticed while working on the wikiheaders updates. A
thorough pass over all the docs would not be terrible, and maybe a simple
script to check for consistency (does everything have a `\since` on it? etc)
might be nice, too.
Add the xdg-foreign-unstable-v2 protocol and use it to create export handles for toplevel windows, which will be used when an external component, such as the file chooser portal, requires it.
This better reflects how HDR content is actually used, e.g. most content is in the SDR range, with specular highlights and bright details beyond the SDR range, in the HDR headroom.
This more closely matches how HDR is handled on Apple platforms, as EDR.
This also greatly simplifies application code which no longer has to think about color scaling. SDR content is rendered at the appropriate brightness automatically, and HDR content is scaled to the correct range for the display HDR headroom.
Renamed the following property define names to have a type suffix to
match other property names.
SDL_PROP_TEXTURE_OPENGL_TEXTURE_TARGET (number)
SDL_PROP_TEXTURE_OPENGLES2_TEXTURE_TARGET (number)
SDL_PROP_WINDOW_CREATE_WAYLAND_SCALE_TO_DISPLAY (boolean)
SDL_PROP_WINDOW_RENDERER (pointer)
SDL_PROP_WINDOW_TEXTUREDATA (pointer)
