PATCH: enable openGL for mythplugins Mac OS X

[gkruse@…]

Mac OS X includes openGL in all installations so we should allow enabling of openGL on the mac even if we don't detect libGL. (it will never find it) I tested this with mythgallery and should also work fine for mythmusic once I finally get it to compile all the way. OpenGL vsync uses x11 specific extensions so we still can't use that. This patch modifies configure to allow the user to use --enable-opengl when configuring the plugins.

I saw a bunch of other patches get applied to the configure script, just making sure this one didn't get lost

Nigel takes care of the Mac OSX port. The other ./configuration changes didn't require any runtime testing so I could commit them safely...

(In [7585]) Closes #483, by applying patch.

Use Qt default sort rather than an O(n^{2) sort.}

[danielk]

Sorry, accidentally closed this instead of #482.

Geoff, applied the change locally, but there seem to be lots of compile errors in the MythGallery OpenGL code?

Do you have local patches for these?

[gkruse@…]

I don't have a patch, this is a "works for me" situation. What version of os x are you running. It compiles and runs for me without a problem on 10.4.2 and 10.4.3. Check out the .dmg I have at ​http://willamette.edu/~gkruse/myth/ The newest one was compiled with OpenGl? enabled.

I was stupid (didn't have the latest gallery source). Your patch works. I am about to check in a slightly cleaner one, though.

[Nigel]

(In [7875]) OS X fixes #483 and #576. Search for headers based on library paths, and force OpenGL for MythGallery on Darwin/OS X

[Nigel]

Do'h - should have tested more thoroughly (like deleted Makefiles before running configure). OK, so it looks like opengl=yes does the same as opengl=detect, which doesn the same as opengl=blah. All of these try to detect the library. I think a patch to configure is in order, but I will have a browse through its history (and mythtv's) to see if there is any good reason for it being, um, broken?

[Nigel]

After some discussion with the other devs, having everything always detect is the intended behaviour. So I have added an explicit check for the AGL Framework. I think the pathname /System/Library/Frameworks?/AGL.framework/Versions/A/AGL is unique enough that it will only be found on OS X :-)
