Made the PNG and UIImage still photo capture routines account for the glitches from photos taken by the front-facing camera.
ImageFilterPipeline now loads arrays properly.

Sync with head repo
Filter pipeline now supports NSString modifiers.
Checking nil for ability to process filters on source picture.

For example;

UIImage *outputImage = nil;
GPUImagePicture *sourcePicture = [[GPUImagePicture alloc]
initWithImage:inputImage smoothlyScaleOutput:NO];

GPUImageFilterPipeline *pipeline = [[GPUImageFilterPipeline alloc]

initWithConfiguration:filterInfo
                                            input:sourcePicture
                                            output:nil];

[sourcePicture processImage];

outputImage = [pipeline currentFilteredFrame];
stringValue scope changed to avoid ARC auto-releasing issues.
Adding filter for adjusting color temperature. An ideal addition to this filter would be a way to set its parameters via a pixel lookup.

Filter for adjusting color temperature.
Merge pull request #436 from omerduzyol/master

 NSString modifier support and nil argument support for self.output added to GPUImageFilterPipeline.
Added a generic chroma key filter for setting keyed areas transparent without needing a blend. Added the white balance filter to the showcase.
Fixed image capture from filter groups, which affected still image filtering on tilt shifts, unsharp masks, and others.
Fixed a problem with the selective blur filter, and others that depend on aspect ratios.
Fixed bug where calling forceProcessingAtSize: will change all subsequent forceProcessingAtSize: calls to undesired sizes. Can now also access the AVCaptureConnection of a GPUImageVideoCamera
Added a high pass and a low pass filter. Fixed compilation issues with GPUImageBuffer on older Xcode versions.

Fixes forceProcessingAtSize: bugs and also allows access to the AVCaptureConnection of a GPUImageVideoCamera
Added a motion detector based on the high-pass filter.
Renamed report_memory due to complaints that it conflicted with other libraries. Fixed a memory leak in GPUImageRawDataOutput.
fix: GrayscaleFilter respects alpha channel and added a synthesize to motionDetectionBlock
Added a new playAtActualSpeed option to GPUImageMovie to have it playback at the actual speed of the source movie. The timing isn't perfect on this yet.

The GrayscaleFilter wasn't respecting the alpha channel
