Drawing with a square pen gives better rectangles
My metapost code is something like:
pickup square pen
draw rectangle with label within (macro call)
label drawing within the rectangle is essentially done with
% prevent wobbling of text boxes with uneven depth
pic := textext("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); %
pic goes into rectangle
Under mkii this worked but under mkiv the text is mangled. To restore
proper text I had to surround this with pen commands:
pentemp := savepen; pickup pencircle scaled 0pt; % apparently any
size will do
% prevent wobbling of text boxes with uneven depth
pic := textext("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); %
pic goes into rectangle
pickup pentemp;
Why is mkii behaving differently and not affected by pen changes?
Is this to be expected from metapost (and thus to be considered normal
behaviour) or did a bug creep in?
Using luatex 0.30.1 and 2008.08.05 18:47 MKIV.
[By the way, sometxt doesn't work here and I have to stick with
textext.]
