2.5.1.dev2

A pre-release before the final release, please help us by testing this!

Release highlights

This is mostly a bug-fixes-and-enhancements release, but we do have a few cool new stuff to showcase!

• We now support and distribute wheels for CPython 3.13 and PyPy for apple silicon.
• The experimental Window class is now subclass-able.
• Added new method Surface.premul_alpha_ip
• The dst argument of Surface.blit now has a default value: (0, 0). This means you can skip this argument if you are blitting a surface at the origin (top-left) of the window.
