GPUImageFilterFactory

/*
*  This is a GPUImageFilter Factory concept, essentially to reuse common GPUImage code that's 
*  required for most GPUImageFilter calls.  Access to these methods then becomes a one liner...
*
*  Be sure to wrap each new Class method you create with @autoreleasepool for improved performance.
