* start removing uses of SkScalarMulGravatar Mike Reed2017-02-06

* make SpecialLineRec::addSegment assert more permissive to accomodate ↵Gravatar lsalzman2016-08-08
| | | | | | | | | | | | | | | | rounding error Because the driving code that calls SpecialLineRec::addSegment uses double precision, when converted back to single precision this may round such that d0 and d1 are the same. This causes the assert to trigger. The simplest thing to do here is to modify the assert to not be so picky and allow the rare/occasional equality.

* limit the number of points in SkDashPathEffect::asPointsGravatar lsalzman2016-07-21
| | | | | | | | | | | | | | | | | | | If the length of a line path is sufficiently long relative to the dash interval, it is possible to cause SkDashPathEffect::asPoints to produce so many points that it overflows the amount that can fit in an int type, or otherwise produce non-finite values, i.e. path from (0,0) to (0,9e15) with a dash interval of 1. This fixes that by capping the amount of points to a sane limit - in this case, 1mil, since that limit is also used in utils/SkDashPath.cpp and has precedent.
