* rules don't really work right for dashed lines if you

* want continuity in segments that go between top/right
|
|
* and left/bottom. For instance, a top left corner
|
|
* with a 1-1 dash is drawn as:
|
|
*
|
|
* X X X
|
|
* X
|
|
*
|
|
* X
|
|
*
|
|
* This is because pixels on the top and left boundaries
|
|
* of polygons are drawn, but not on the bottom and right.
|
|
* So, if you have a line going up that turns the corner
|
|
* and goes right, there is a one pixel shift in the pattern.
|
|
*
|
|
* So, to fix this, we drawn the top and right in one call,
|
|
* then the left and bottom in another call, fixing up
|
|
* the dash offset for the second call ourselves to get
|
|
* continuity at the upper left.
|
|
*
|
|
* It's not perfect since we really should have a join at
|
|
* the upper left and lower right instead of two intersecting
|
|
* lines but that's only really apparent for no-dashes,
|
|
* which (for this reason) are done as one polygon and
|
|
* don't to through this code path.
