- added "image" to json commands to insert a jpg image/icon from the flash partition - added optional center/right alignment to "textbox" json command - google calendar content: added optional colors, different color per calendarid - improved ordered dithering, works also with unevenly spaced color tables. This is to be used with graphs etc., not suitable for photos (use floyd steinberg for photos) - improved flyod steinberg dithering (fix some bugs) - added preview rendering for 4bpp images - log tab now scrolls to the top on entering - added optional perceptual color table to tagtypes (for rendering previews, for example to display darker yellows on screen while keeping the 255,255,0 color to the tag - drag/dropping in an image to a tag while holding shift key now uses ordered dithering (default is floyd steinberg) - some tagtype improvements
