Qx a new routine for CMBASE, following change-width
QY
def center-on(expr x) = if not monospace: % change width for symmetric fit
r:=r+2x-w; w:=2x; fi enddef;
Qz
Qx in SYMBOL, the elementary division operator
x3-. 5dot_size=hround(. 5w-. 5dot-size) ; w: =r :=2x3;
QY
x3-. 5dot_size=hround( .5w-. 5dot-size) ; center-on(x3) ;
Qz
Similarly, whenever the construction "w:=r:=2x*" appears, change it to
"~enter,on(x*)~~. This happens in the programs for elementary division operator
(as noted above), large triangle, large inverted triangle, lattice top,
lattice bottom, dagger mark, double dagger mark, club/diamond/heart/spade suit
(all in SYMBOL), plus the diamond operator and universal quantifier in SYM.
The following additional change needs to be made in the programs
for lattice top and lattice bottom:
Qx
xl=x2=good.x .5w; center-on(x1); lft x3=hround u; x4=r-x3;
QY
xl=x2=good.x .5w; center-on(x1); lft x3=hround u; x4=w-x3;
Qz
Ox in SYMBOL, at end of zero-width slash
labels(l,2); zero-width; endchar;
QY
labels(5,6); zero-width; endchar;
Qz
(I sincerely hope there won't be any more!)
