A couple new filters
Integrated the two new filters into the showcase.
Fixing commit.
Made enum in the filter showcase more amenable to version control (per Alaric Cole's suggestion).
Added preliminary support for a still photo camera. This isn't working quite right yet, since it's not processing images at the right size.
PolarPixellate Shader based on Vid by Toneburst
StretchDistortion
Fixed case sensitive bug in file name.
Removed invalid OpenGL ES 2.0 call

Polar pixellate and stretch distortion filters
Incorporated the polar pixellation and stretch filters in the showcase.
Fixed the sizing issues I was having with the still photo capture, and fixed the preview input on iOS 4.0. The still camera is now functional on every device but the iPhone 4.
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.
