Animations are structured in AnimationData as follows:
Animations are structured in AnimationData as follows:
.colors contains .color_count*3 uint8_t values for R, G and B.
.colors contains .color_count*3 uint8_t values for R, G and B.
.offsets contains the frame start offsets within .data + the length of the data. (So
you can always do something like `for (int i=anim.offsets[i]; i<anim.offsets[i+1]; i++)`.
Accordingly it has a length of .frame_count+1.
.offsets contains the frame start offsets within .data + the length of the data. (So
you can always do something like `for (int i=anim.offsets[i]; i<anim.offsets[i+1]; i++)`.
Accordingly it has a length of .frame_count+1.
.data contains all frames data with a run-length compression with escape char 255.
This data references the index of one or multiple pixels in .colors. It starts at the
top left pixel and walks each row to the right before starting the next row.
To decode it: Start at a frame (indicated by .offsets). Get one byte as x.
If x is <255: This is a single pixel of color x.
if x is 255: Run-length-encoding. The next byte indicates of often the byte after that
will be repeated. So, {255, 4, 10} is equal to {10, 10, 10, 10}.
A special case that may happen in larger GIFs is that there are more than 255 repetitions
of a color. Those will be split, so 355*color #10 will be: {255, 255, 10, 255, 100, 10},
e.g. 255*10 + 100*10. Usually this shouldn't need special handling within a decoder.
Regarding colors in .data:
Color 0 means "keep the color from the previous frame". This color should never appear on frame #0.
Color 1 means "show the background color".
All other color values point to a color in .colors - with an offset of 2.
So if in .data there's a color 3, paint this pixel in .colors[1].

.individual_delays contains either 1 or .frame_count delays. They are given in ms and
indicate how long the matching frame should be displayed. If all times are equal, then
it contains only one entry and .individual_delays will be false.
