Add basic animation support

[mriale]

Add basic support for animation:

• Setting number of frames
• Moving from frame to frame
• Playback
• Loading IFF ANIM
• Saving IFF ANIM

Need to make palette into an object so it can be easily be used in animation frames. Currently the palette is stored globally in several variables:

• config.pal - current palette used almost everywhere. This is color skewed to make sure each palette entry is unique and color cycled colors don't get collapsed into the same color.
• config.backuppal - palette storage during color cycling
• config.truepal - true color palette (not color skewed)
• config.loadpal - palette that was loaded from a file

Rather than store the palette with every frame, ranges of frames need to reference keyframe palettes. DPaint V implements this but the GUI for it is not very usable.

I want to add an animation toolbar on the bottom of the screen with VCR controls and a slider:

|< << > >> >| ----------- + - P

To the right of the slider:

• Add frame
• Remove frame
• Palette key frame indicator

Added image but no code yet.

Good luck!
