SDL_BlitSurfaceScaled() is more flexible and uses the SDL_SoftStretch() fast path when possible. Having two surface scaling APIs was confusing, especially when one of them has unexpected limitations.
This was done to SDL_DisplayMode for consistency with SDL_Surface and gives it a type so we don't have to do casts in SDL code.
I considered switching to an ID and hashing the driver data, etc. but all of that involved a lot of internal code churn and this solution gives us flexibility in how we handle this in the future.
After consideration, I made this renaming global across the project, for consistency.

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 commit fixes the attribute list in the WGL and GLX code when requesting a floating point pixel format. The name of the attribute was missing in the list.
Fixes libsdl-org#10189
This allows the numpad to work as the user expects based on the numlock state. If the application needs to distinguish the keys, it can check to see whether the scancode is a numpad key or not.
The new function includes the cursor position so IME UI elements can be placed relative to the cursor, as well as having the whole text area available so on-screen keyboards can avoid it.
* Don't need to initialize values already zeroed
* Added debug message logging
* Don't send duplicate SDL_EVENT_TEXT_EDITING events with empty text
* Send the length of selected text in the SDL_EVENT_TEXT_EDITING event
* Fixed potential crashes when out of memory
SDL_StartTextInput(), SDL_StopTextInput(), SDL_TextInputActive(), SDL_ClearComposition(), and SDL_SetTextInputRect() all now take a window parameter.
This change also fixes IME candidate positioning when SDL_SetTextInputRect() is called before SDL_StartTextInput(), as is recommended in the documentation.
