First version supporting the new record and play feature which allows
to `record` a number of API calls and lets you replay them at a later
point of time. This could be the basis for creating an Editor and
other more advanced features. While I tested the functionality there
still could be a number of bugs and I would recommend waiting
until all bugs are removed before using it.
Previously the popup buffer state was stored inside the group
panel layout instead of the window layout. This caused
overdraw for popups and the underlying window. To fix that now
all popups are stored inside the root window panel layout
and everything is drawn correctly.
While dividing previously spared me from a lot of work and problems
it is probably best to have everything working for every or as many
platforms as possible. Some platforms fail to provide good ways
to support everything (e.g.:X11 does not have pixmap clipping with
different width/height or alpha-blending) but all OpenGL demos
outside allegro (needs some additional work) should be able to run.
