Fix bug with break/continue inside of a foreach or forindex: Don't pop
the vector/index inside OP_EACH, do it at the end of the loop.
In the process, discovered and fixed a scary corruption issue with
continue; it never really worked right, although simple usage was
likely to get away without crashing. Both the continue's OP_BREAK and
the cleanup code at the end of a loop would pop the "mark" stack,
leading to an underflow. Introduced an OP_CONTINUE which adjusts
stack but doesn't change markTop
Re-inline the PUSH macro. This thing is called all over the place
from the inner loop. If the problem is intra-expression side effects,
then just use another expression in the macro.
Return an empty vector when requesting zero-length subvec, not nil
Have call() return the call stack in the error vector; see docs on
plausible.org/nasal or ask Andy about this feature.
Default closure()'s level argument to zero, not nil
Add an optional "file name" argument to compile()

Plug a memory leak with GlyphSigns.
specify the same texture in the "foo.lighted" and "foo.unlighted" material
entry. This also allows to drop the state cloning and thereby solves the
most urgent apt_signs.cxx TODO. :-)

- clone state less often: not once per sign element, but once per material
switch (TODO: clone only once per material)
got plib's lowres red-white chequer-board pattern along with an error
message, and not ours ... which is much prettier, but also bigger.
(Should we downscale it?)
- add commands @size, @material, @light
- make "BlackSign" texture default
- make @B, @R, @L, @Y open close their frames automatically (this can be
avoided by setting the @material manually)
- add number variants for those 4 sign commands: @Y2, @B5, etc (according
to the spec; defaulting to the respective biggest panel size, i.e. @B = @B3)
(detailed description will be added to $FG_ROOT/Docs/)
uninitialized data bug in naHash_cget(). When the hashcode field of
naStr was introduced, I forgot to set it in this function, which
creates a temporary naStr on the stack.

describe where in the texture a letter or symbol begins and where it ends.
(range 0-1). <xscale> defines a horizontal scaling factor.
