Sam Lantinga 334962b056 Enhancements for SDL_PremultiplyAlpha() 
The function can now convert between pixels of different formats, and takes a parameter to control whether the premultiplication is done in sRGB or linear space.

Also added SDL_PremultiplySurfaceAlpha(), which can premultiply the pixels of a surface in-place.

Simple DirectMedia Layer (SDL) Version 3.0

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting with README.md. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.

Enjoy!
