automatic resolution/color depth detection now supports segmented (multiple files) sequences
slight performance improvement (Y,Cb,Cr masking entirely skipped when not in use)
implemented SSIM (structural similarity), original method and video method
added technical documentation about the internal image processing methods
bumped the max. filter length in scaling routine to 64 taps (roughly sufficient to properly downscale 1080p into QCIF)
version 0.91
fixed hang/crash in Open Dialog on PowerPC machines
fixed split view divider refresh issues on MacOS 10.4
version 0.9

Macroblock number and magnified Macroblock move out of the way whenever the mouse pointer is nearing
PSNR is indicated in the frame number slider by a color bar (RED=20 dB and below, YELLOW=25 dB, GREEN=30 dB and better, BLUE=perfect match)
in play mode, the number of frames per second is selectable
changed scaling of displayed sequences from linear to "nearest neighbor" in order to identify individual pixels better
released the source code for this version, license: GPL V2
Version 0.6
compiled as universal binary, runs native on Intel processors
added image preview to open dialog for instant verification of correct image dimensions
