fixed gpuimage benchmark suite for live video streams
updated video processing benchmark - CoreImage processing now uses entire screen
Check that the session is running before trying to process frames - fixes crash when backgrounding app
Fix type in GPUImageHueFilter
Adding .svn to the ignore list for hybrid projects.
Marking the headers as 'public' so you can use the project as a direct dependency.
Adding missing rotation mode.
Fixing some of the exiting ones.
Fixing issue where the first frame would always be white because glUniform1i was failing after this switched shader programs unexpectedly due to the need to initialize the second filter.
Allow for chaining the output image size.
Re-working GPUImageVideoCamera to use the YUV->RGB transform method shown in Apple's AVBasicVideoOutput example because it produces results closer to that of the built-in camera.
Making GPUImageMovie do the YUV->RGB conversion via shader rather than asking AVFoundation to do it.
Update the view geometry on frame changes so we don't end up stretching the image if our view gets animated.
Don't enable the audio track if it's already enabled. It can cause the system to have two AVAssetWriters for audio going at once.
Lots going on here, but there was no logical way to separate it into smaller changes.

Allowing GPUImageMovie to take an AVPlayerItem for playback as well as an AVAsset in order to allow it to play AVComposition objects. When sourcing from an AVPlayerItem, it now uses CADisplayLink to handle the timing to ensure proper A/V sync.

Adding GPIImageMovieComposition specifically for reading from an AVCompostion object in non-real time. This is primarily so it can be connected to a GPUImageMovieWriter in order to render a composition to file.

Lots of changes to how audio/videoInputCallback(s) are managed to make rendering to a file reliable.
Moving target to iOS 6 so weak references will work as expected.
Merge branch 'master' of https://github.com/PedestrianSean/GPUImage
Notify delegate that play has finished in more cases
Change delegate to call back in end processing
Allowing the movie writer to be paused when in callback sync mode. This is primarily useful when the app is going to the background and you're rendering in non-real-time.
Fixing an issue where the write loop would keep retrying even when the writer had been canceled.
GPUImageVideoCamera: Add -(BOOL)addAudioInputsAndOutputs and -(BOOL)removeAudioInputsAndOutputs to manage audio inputs independent of audioEncodingTarget

Previously if you add or change the audioEncodingTarget the inputs are recreated, which triggers a pause in the app.
GPUImageVideoCamera: begin & commit configuration when removing inputs and outputs
