- think about mapping. _If_ we do everything in logical

coordinates (which would solve the probs for stroke

widths and text offsets), then we would have to

2004-03-18 09:41:15 +00:00

recalc scaling for every drawing operation. This is

because the outdev map mode might change at any time.

Also keep in mind, that, although we've double precision

float arithmetic now, different offsets might still

generate different roundings (aka
