Calixte Denizet b3dccd66ab Enforce line width to be at least 1px after applied transform ...

* add a comment to explain how minimal linewidth is computed.
 * when context.linewidth < 1 after transform, firefox and chrome
   don't render in the same way (issue #12810).
 * set lineWidth to 1 after transform and before stroking
   - aims fix issue #12295
   - a pixel can be transformed into a rectangle with both heights < 1.
     A single rescale leads to a rectangle with dim equals to 1 and
     the other to something greater than 1.
 * change the way to render rectangle with null dimensions:
   - right now we rely on the lineWidth set before "re" but
     it can be set after "re" and before "S" and in this case the rendering
     will be wrong.
   - render such rectangles as a single line.
