Turns out that there isn't a strong OpenGL naming convention for "Delete" ...
WGL offers "wglDeleteContext" but the GLX equivalent is "glxDestroyContext"
and then EGL sealed the deal by going with Destroy as well! Since it matches
SDL3 naming conventions (Create/Destroy), we're renaming it.
Fixes#10197.
SDL_Surface has been simplified and internal details are no longer in the public structure.
The `format` member of SDL_Surface is now an enumerated pixel format value. You can get the full details of the pixel format by calling `SDL_GetPixelFormatDetails(surface->format)`. You can get the palette associated with the surface by calling SDL_GetSurfacePalette(). You can get the clip rectangle by calling SDL_GetSurfaceClipRect().
SDL_PixelFormat has been renamed SDL_PixelFormatDetails and just describes the pixel format, it does not include a palette for indexed pixel types.
SDL_PixelFormatEnum has been renamed SDL_PixelFormat and is used instead of Uint32 for API functions that refer to pixel format by enumerated value.
SDL_MapRGB(), SDL_MapRGBA(), SDL_GetRGB(), and SDL_GetRGBA() take an optional palette parameter for indexed color lookups.
This reverts commit 3c90b1c1f6.
It turns out this is problematic for sdl2-compat. We're investigating a more complete separation between SDL2 and SDL3 surfaces, but in the meantime, I'll fix the breakage.
The result of SDL_RaiseWindow is ultimately subject to window manager policy, particularly if the request would result in stealing focus from another window. Document that this is only a request, and if successful, will result in a focus gained event along with the input focus flag being set on the window.
I didn't add a note to SDL_DestroyWindow() because we actually protect against this case now, but it's useful information to know conceptually when working with the renderer.
Any parameters (key/value pairs after the '?' in a URL) that have a keyname
that starts with `SDL_` will be put into Emscripten's environment variable
emulation table at startup, before SDL_main runs.
This lets users set hints the same way they might set them from a shell's
command line on a desktop platform:
For example:
`https://example.com/my_sdl3_application.html?SDL_RENDER_DRIVER=software`
Fixes#10154.
This was added by the Unreal Engine to handle the input focus for popups and dialogs, window types for which SDL3 has built-in, cross-platform support.
This was only ever implemented in X11, and the only purpose was to hint that a client application may want to call the SDL_SetWindowInputFocus() function, which has since been removed, rendering it pointless now.
This was added to SDL2 for the Unreal Engine's implementation of menus and dialogs on X11, window types for which SDL3 has added built-in, cross-platform support.
Remove this function, as it was only ever implemented for X11 and is now basically useless aside from allowing annoying or malicious client apps to discretely steal focus. As the documentation states: "You almost certainly want SDL_RaiseWindow() instead of this function."
