Enhance: support reading Aseprite files

[NObodyGX]

Supporting reading of Aseprite (.ase/.aseprite) files could streamline animation workflow and sprite compositing. Is this in considering?

TL;DR: You're in luck because the pyglet repo already has a partial Aseprite codec.

Where Do I Copy it From?

Note

It might require further work to adapt its output for Arcade's Sprite types

Code at https://github.com/pyglet/pyglet/tree/master/contrib/aseprite_codec

Step 2: Try Loading Your Assets

i.e. "Do my layer modes break?" Per the pyglet aseprite codec README:

This codec is fairly complete, with the limitation
of only supporting "normal" blending mode for layers.

Even if you do, try loading them anyway and take notes on how badly things break.

If anything breaks, try one or more of:

• adding the modes yourself (harder, only if you're up for it)
• using the Aseprite Lua API to auto-export assets (lazy option)

Step 3: Time for Adapter Code?

If it works or if you fixed it, you might need to convert texture formats:

• The aseprite codec seems to produce pyglet image data objects
• Arcade's Sprite type might not accept those directly

This is expected since the contrib folder's more proof-of-concept examples than ready-to-use features. Each breaks the normal pyglet rules in at least one way:

• No mandatory external dependencies (the Qt example)
• Code quality / completeness (the Aseprite example)
