This is the first step to allowing non-segments in the line chain. External routines cannot be allowed to change the line chain without going through the internal routines. To accomplish this, we remove the Vertex() and Point() access routines and only leave the const versions. Transformations are given for both points as well as the chain itself.

the DXF declared version, the acad version reading it *and* some

system variables to be put in the header handled only by newer acads

Also before R15 unicode simply is not supported (you need to use

bigfonts which are a massive PITA). Common denominator solution:

use Latin1 (and however someone could choke on it, anyway). Sorry

Windows)

|
to 255 bytes records (it was later raised to 2048); since I'm lazy
|
|
and text so long is not probable I just don't implement this rule.
|
|
If someone is interested in fixing this, you have to emit the first
|
|
partial lines with group code 3 (max 250 bytes each) and then finish
|
|
with a group code 1 (less than 250 bytes). The DXF refs explains it

in no more details...
