--- Comment #18 from Armin Le Grand (CIB) <Armin.Le.Grand at me.com> ---
@V Stuart Foote: Has nothing to do with each other except that it uses Canvas
for rendering. Until today Slideshow uses Metafile to transport graphic info -
I wanted to change that to primitives (all info is there, Draw/Impress is
completely on primitives) but was interrupted hard at that time, sigh.
It could be changed to primitive rendering any time - would be better for
handing over anyways, primitives are UNO API objects. Together with a primitive
renderer per system that uses HW acc directly (which also can be used in apps
editviews display then) would be perfect.
The current primitive renderers render to vcl - that was the general and
fallback implementation for primitive redering, pure renderers for e.g.
OpenGL/DirectDraw or whatever would be possible anytime. From my POV that would
be the better way, instead of putting more and more stuff 'below' vcl. Just my
2ct...
