This is an update to the preview release of the new SDL 3.0 API.

Here are some of the highlights since the last preview:

• Fixed a crash when rendering lots of content using the Vulkan renderer
• Fixed text input being delivered when SDL_StartTextInput() hasn't been called
• Added support for raw keyboard events on Windows
• Fixed a performance regression initializing controllers on Linux
• Separated the joystick power state into battery status and percentage
• Added an optional user parameter to main callback entry points
• Case insensitive string comparison functions are no longer affected by locale
