* Move auto-adjustments for transformation matrices from the VideoTranscodingSamplePipeline constructor to the new ScaleToFitFrameProcessor. * Add GlFrameProcessor#getOutputDimensions() to allow for GlFrameProcessors with different input and output dimensions. This is a prerequisite for Presentation. * Tested with unit tests (and manually just in case). * A follow up CL will implement change the FrameProcessor input to be scale and rotate values as requested by the user. This was kept out of this CL to reduce CL review size. Presentation will also be implemented in a follow up CL. PiperOrigin-RevId: 434774854
