Timestamps are now passed through the filters, so movies are now filtered and recorded at the correct framerate.
Added iOS 5.0 texture cache support to GPUImageMovie, improving performance of movie playback.
Added ability to override filter processing sizes for thumbnail use. Started adding hooks for audio support.
Fixed the unsharp mask filter to avoid double frame updates. Added a check to prevent recording-halting frame timestamps.
Started adding audio recording support, but live video has broken timestamps and prerecorded video is dropping audio samples.
Still attempting to get audio recording working right for live video. Made audio samples record on background thread so they didn't jam things up.
Live audio recording now has correct sample timings, thanks to Alaric Cole.
Input movies can now be synchronized with output movie writers so that not a single frame or audio sample is lost.
Added the ability to set orientation of captured UIImages. Experimented with direct copying of bytes when setting up images, but that's slower than redrawing for some reason.
Trying to add iOS 5 Texture Pipeline
Fixing a type that I added
Merge pull request #58 from fattjake/master

I've attempted to add the fast texture pipeline to the rawData class.
Fixed the low-res photos being captured by the GPUImageStillCamera.
Fixed the raw data reads using the texture caches. Added 1 s fragmenting on recorded movies to prevent against early termination. Fixed the custom filter in the showcase.
Added a GPUImageTexture class for importing OpenGL ES textures and scenes into GPUImage. Updated the CubeExample to show how this works.
Added a tilt shift lens filter.
Added a 3x3 convolution kernel filter, and an embossing one based on that. Fixed a couple of potential memory leaks with the movie writer and raw data output.
Added a Canny edge detection filter.
Added a smoother toon filter.
Updated the CubeExample to show how to use a share group to couple with GPUImage's OpenGL ES context.
