I am not sure if qscreen should be among wd
commands at all.
"qscreen" should be called qdevice (or qcontext),
since it's applicable to selected output media
like printer. Thus it is more appropriate
for gl2 commands, where destination can be a printer.
Here's usecases from J library
g:\math\j601\system\classes\view\viewmat.ijs (1)
max=. 2 3 { 0 ". wd 'qscreen'
g:\math\j601\system\examples\games\solitaire\main.ijs (1)
xy=. 2 3{".wd'qscreen'
g:\math\j601\system\examples\games\solitaire\options.ijs (1)
xy=. 2 3{".wd'qscreen'
g:\math\j601\system\extras\util\debugs.ijs (1)
5 { 0 ". wd 'qscreen'
All but last should use qm. Last is probably
a hack left from the old 72/96 dpi hacking days,
fixed in j601; thus should not be used.
Removing qscreen from wd and make an appropriate
command in gl2 would eliminate this confusion.
Not all things are needs like millimeters.
Note: in Java the only useful thing it reports
is DPI, which again makes more sense in gl2
in the context of current device like screen,
paper etc.
