[vlc-devel] [PATCH] 64-bit support for Mozilla plugin on MacOS

This patchset is an update to my work from many months ago on the
64-bit browser plugin on Mac.  While I still have no explanation
for some of the mysterious crashes from the previous patchset,
these new patches do things in a slightly different way, and I
have not experienced a crash with them.  Aspect ratio changes,
resizing, and fullscreen mode are all supported (though the 
support for fullscreen mode is handled in the plugin code, not
in the vout display).

(Note that there are only 3 patches in this set.  The subject lines
may say [PATCH x/8], but the other 5 patches are just private
changes for debug purposes.)

[PATCH 1/3] Add CALayer module

This patch adds the new calayer.m vout display module used by the
new plugin code.

[PATCH 2/3] Add coreanim.m for Core Animation code that must use Objective C.

The browser plugin is written in C++, but the Core Animation libraries can only
be accessed in Objective C.  So this file contains all the Objective C code
for Core Animation support.

[PATCH 3/3] Use Core Animation drawing model, Cocoa event model in 64 bit plugin.

This patch actually updates the plugin to use the Core Animation support from
the above two patches.  All the code is #ifdefed out to only compile on the
64-bit Mac platform.  (Some 32-bit browsers do not support the Core Animation
drawing model.)  We could add some code to check at runtime whether the browser
supports Core Animation, but for now it is easiest to only use Core Animation
on the 64-bit platform.

All this work is done by Veetle.
