Nice! This would be great to include as example game in 4.4.0 - with the
option to build either for Allegro or AllegroGL (which should be
included in it). Not sure how it would work in detail.

Which animation is that, and why does it break?

Would it be hard to use an alpha bitmap in that case? I.e. just have two
textures on disk, use the pink one for the Allegro version, and the
alpha one for AllegroGL.

Indeed. In one of the meetings, we said we want to "merge" AllegroGL
into 4.3.10. Where merge could mean nothing more than just copying it in
there, but still keep it as separate library.

Any reason the patch shouldn't be applied to SVN?
