The question is: is it really possible for one toplevel to contain
components having different GraphicsDevice's (and/or different
GraphicsConfiguration's)? Or may I assume that all and every
descendant components of a toplevel window use the same GC that the
window uses (and therefore the Container.checkGD() may safely be
removed)?
We should enforce that all components within a toplevel have the
same GC. If checkGD does that I wouldn't remove it.
"Asserts" are fine as long as they are simple and fast. But if we're
sure we don't have several GC/GDs per toplevel window, then I don't see
much reason to waste time recursively traversing the whole hierarchy of
components of a container when it gets added to another container.
Perhaps it would make sense to move the graphicsConfig member to
the Window class and use its value for
Component.getGraphicsConfiguration()? A component not currently
contained in a toplevel window obviously should have a null GC. Thoughts?
