Here, the void *engine_data holds any engine specific

the current XRImage structure (minus certain things).

About your second point, The gl-engine can render to a texture or a
pbuffer, there is no problem with this, as long as it doesn't swap
the buffers. But as raster said, it is not possible if we want to
get good performances with OpenGL, rendering to a texture is slow

But the 'problem' goes deeper than that. Right now the
argb data itself (ie. the result of loading things given only
the file/key/load_opts combo) may be shared by several cached

You're using the image struct's extended_info pointer,
in the sdl engine, to hold an engine-specific surface (namely,
an sdl surface), I added an extra void *engine_surface for
