Does this strike anyone as odd? There seems to be a kind of mismatch here.

There is this great Aqua UI designed and presented by Apple.
There are several controls designed and presented by Apple.
There is an API that lets you build your own controls from scratch.
But you cant draw them to look like Aqua.

I understand that "many" people are using the new control APIs. Most of
them from what I can tell are building composite controls (that is
controls made from other controls). While it is possible to build a low
level raw control, it is virtually impossible to make it look like the
rest of the interface.

Maybe someone ( salvor? ) should file a bug.
