Per-object blend mode

[CelticMinstrel]

You can currently set a blend mode on layers. It would be nice if you can also set this on individual objects.

This seems like a useful enhancement,
One possible approach could be to allow objects to optionally define their own blend mode while defaulting to the layer’s blend mode for backward compatibility. During rendering, the object-level blend mode could take priority when set, otherwise falling back to the layer setting.
It might also be worth considering how this would be represented in TMX/JSON (e.g., an optional blendmode attribute on objects) to keep it consistent with layer-level support.
Curious to know if there are any constraints or concerns around performance or rendering order when applying blend modes per object.
