I am not sure wether I should simply copy and paste the old DTM implementation,
|
|
or rewrite it from scratch.
|
|
|
|
The old DTM system problaby doesn't perform that well, but seems to be quite
|
|
stable and complete.
|
|
|
|
If I would rewrite it from scratch, it would probably be faster, and
|
|
hopefully more efficient.That won't be too hard, especially since I have
|
|
direct data access now. (TClient FTW!)
|
|
|
|
Rewrite from scratch it will be, I guess.
|
|
And AreaShape will be turned into a {$I }, inline simply doesn't cut it.
