You raise an interesting point I have been thinking about. Currently 15!:0
targets arguments of various types and always requires boxing each. This has
never been an issue. However the opengl API has a large class of calls,where
performance may be an issue, that have scalar args of the same type. It
would be fairly easy to introduce a new 15!:x that took a list of scalars.
I'm not sure if this is worth it, but would consider it if presented with
arguments.

A few more notes, working through the opengl lab:
── (18 of 42) Isigraph Control (ctd) ────────────────────────
Calls with all scalar args are defined to box each scalar (as
required by cd) and to be rank 1. This allows calls with a
simple scalar list and allows application to tables.
Wouldn't unboxed right arguments with 15!:0 be radically more
efficient for these cases? (Not that efficiency should be
a primary concern, but in this case it also seems like it
should be simpler.)

modifiers) is often added for the common case. For
glVertex... the added definition is: glVertex=: glVertex4d
That's not completely accurate. (Not that I'm complaining,
I'm talking about minor rough edges here, and releasing even
a small piece of software can involve a lot of work and time.)

I'd also be inclined to use

Here, I got an error:
error in: jijs_jctrl_fkey
domain error: gluDeleteQuadric
gluDeleteQuadric obj
Also, when I restarted the lab without creating a fresh J
session, no opengl rendering window would appear (though
the buffer manipulations without a window seemed to work
just find).
When I restarted the lab in a fresh J session, section 32
seemed to work just fine, so I'm suspecting a race condition.
FYI,
