Subject: SDL: video/quartz cleanup
while doing some experimental changes in the quartz code, I was annoyed
by having to recompile that one big .o file over and over again. So I
decided to finally realize one TODO: properly splitting the code over
multiple files :-).
With two exceptions, I didn't make code changes, only rearranged files
and added new headers. Since there are several new files, making a
patch didn't work out so well, so I decided to just send you all the
new & modified files.
The one source change I made is related to showing/hiding the mouse. I
renamed cursor_visible to cursor_should_be_visible and cursor_hidden to
cursor_visible; I think that makes reading the code easier.
Then I added two new functions: QZ_ShowMouse and QZ_HideMouse. They
help manage cursor_visible (the former 'cursor_hidden'). Finally I
replaced the Carbon ShowCursor/HiderCuror calls by [NSCursor hide] and
[NSCursor unhide]. The API docs are not conclusive, but it might be
that with those the "cursor_visible" (former 'cursor_hidden') hack may
not be necessary anymore; however so far I didn't test this hypothesis,
so I left that in.
The other change was to remove in_foreground and use [NSApp isActive]
instead: Manually keeping track of whether we are in the foreground is
error prone. This should work better in some corner cases.
