What about nesting arrays in data structures without using drawing
instructions? For example, three templates, something like the following:
1. rgb values [struct rgb float value]
2. histogram with array of rgb values [struct histogram array values rgb]
3. master-list with array of histograms [struct histograms float dummy-variable
array master-list histogram]
Traversing would only happen once for [append histograms dummy-variable]. You
could then get and set everything else (e.g., array sizes and rgb value) using
[setsize] and [element]. And maybe use [until] with a counter to dump the rgb
values of a given histogram from the master-list.
