I’m running through the viewmat lab and get the following on the last three
lines of page 14:
── (14 of 20) RGB ───────────────────────────────────────────
A left argument for viewmat of 'rgb' means that the right
argument is interpreted as a table of RGB color integers. The
initial size is exactly that given.
For convenience, the utility viewrgb is defined as:
'rgb' & viewmat
For example, read in a bitmap file. Each number is an RGB
color integer.

I haven’t checked any other versions.
