Thanks for the note on Linux.
I noticed that too, but I wanted a clean case first.
It turns out Linux represents color not
in ints (as glpixels does: ARGB, where B=256|c),
but in 4-element arrays of bytes, always RGBA, R=c[0].
I have been experimenting with offscreen
isisgraph which is resized with other
visible isisgraph as shown in fontscale.ijs.

The non-unique sparse elements is due to a wd bug. I forget the details.
One variant of this has been fixed in the next beta so please test
again. A buffer overflow, rather than resizing and continuing, gets
confused as an error with a curious number.

Interesting problem. I need to dig a bit deeper, but suspect fixing it
may beyond the scope of the 601 release.
The problem is that the memory buffer for an isigraph's pixels is only
created 'when necessary'. Your h isigraph is hidden and doesn't get
paint events when resized and what
A quick test shows that using another unshown form works OK.
1. remove cc h isigraph from form create.
2. change f_g_paint as follows:
f_g_paint=: 3 : 0
glsel 'g'
wh=. 2*glqwh''
wd'pc abc;cc h isigraph;setxywhx h 0 0 ',:wh
glclear ''
q=. 16b010101*av2 av2.|: 256|q
wd'pclose'
That's most adequate and the speed or
memory difference is undetectible.
So it's not as much a workaround, but rather
the proper way to do the thing.
Thank you.

I think the documentation for glpixels should mention that x y are in logical
unit (pixel or twips), but w h are always in pixels. Simiarly for glqpixels and
glpixelsx.
