- I wasn't going to bother, but...
-
- If they were really taking least common denominator, then they wouldn't
- have implemented it at all.
-
- That said, if they wanted to make dashed lines work on a Mac, it's not as
- easy as saying PenSize(6,6) and doing the same thing. This is so because
- the pen that is used when drawing a line (with standard QuickDraw) is
- rectangular (or in this case, square), so if the dashed line were along a
- diagonal, it would look really bad.
-
- So if they wanted to improve the dash support to thicker lines and have it
- look right, then they'd have to deal with this problem by writing a
- separate line drawing routine (probably drawing them with polygons -- as if
- it wasn't slow enough as it is). The complexity mounts.
-
- And then, once they did this, they'd also have to add a feature like this
- to the Windows version of ODF so they would both have the same
- functionality.
