Eirik Aavitsland 73573fce29 Fix huge painting artefact of certain dashed lines 
The artefacts appeared for square-capped dashed pens when the end of
the line fell a tiny fraction into the start of a new dash. At that
point in the dashing algorithm, accumulated precision errors in the
'length' variable could make it slightly differ from the actual length
between the start and end points of the line fragment. Although both
values would be "almost zero", the rasterizeLine() function's square
capping would make the error very visible; see the bug report.
Fix by calculating the precise length of the last line fragment.
