Summary: ClientDC paint not being shown on OS X with 2.8

Initial Comment:
Since moving to wxWidgets 2.8, drawing done with a ClientDC (outside a paint
event, via the paint method) is not being shown until the window is invalidated,
on OS X only.

This can be seen in the cursor sample in bigdemo; the red circle shown on click
to mark the hotspot does not appear until the Choice is dropped down and covers
the window.

For some reason I can not log into rubyforge to comment on this bug,
so here is the comment for now:

Based on what I have read on the DialogBlocks mailing list 2.8 is now
drawing using core graphics on OS X.

Julian Smart wrote the following:

"You could try editing include/wx/mac/carbon/chkcnf.h and setting
wxMAC_USE_CORE_GRAPHICS to 0 and recompiling, since this mode is
rather new and there are a few issues with it. In particular,
wxClientDC does not work well with core graphics mode on - Mac OS X
prefers it if you do everything in your paint handler."

I think we should set wxMAC_USE_CORE_GRAPHICS to 0 for now until the
bugs are worked out.

The DialogBlocks mailing list is here, I think you have to subscribe
to the group to read messages.
