Realtime JPEG Compression Shader (TRUE I/DCT)

This plugin implements a real-time approximation of JPEG compression artifacts using:

1. Discrete Cosine Transform (DCT)
2. Quantization using standard JPEG luminance matrix
3. Inverse DCT for image reconstruction
4. YCbCr color space conversion

I plan on adding much more customization and block sizes in the future, this is a very new project.

Since this seems to be the only actual simulation that uses Discrete Cosine Transforms I think it's a fair starting price however I may adjust this in the future.

To use the shader first install the plugin to your project, then use the CVar r.JpegCompression 1 to activate the shader.

CVars:

r.JpegCompression [0,1] Enable/Disable the shader.

r.JpegCompression.Quality [0 - 100] Quality Scalar for the compression table (all values).

r.JpegCompression.BlockSize [8,16] Currently the shader only supports 8x8 (Classic JPEG) or 16x16 but I plan to add more block sizes in the near future if this does well.

r.JpegCompression.Debug [0,1] Enable/Disable the grid/blocksize overlay.
