[105/1] If. Second byte is zero for block-if or one for inline-if. The
next word is the number of words to skip (including the count itself) if
the condition is false.

[106] Else

[107/3] ImageSeq (seems to do nothing?)
[107/3] ImageSeq (seems to be a obsolete variant of Animate, for animations
that play only once)

[108/3] ImageLoop (seems to do nothing?)
[108/3] ImageLoop (seems to be a obsolete variant of Animate, for looping
animations)

[109] PopUp. Values taken from the stack is one plus the minor code.
