commit 324e5571cafe7838a1d3ecd5cb2b3dd7e8d54bbe
Author: Guillaume Munch <[email protected]>
Date: Thu Sep 29 20:20:33 2016 +0200
Fix borders of InsetMathGrid
* New virtual functions leftMargin() and rightMargin() to get rid of
drawWithMargin()
* Factor and rewrite code for borders.
* Fix several offset calculations.
Known issues:
* Borders of multicols look too good and do not correspond to the pdf
output. (non-regression)
* Bounding box for Hull (Regexp) not pixel-perfect.
* Bounding boxes of Diagram, XYmatrix, are too tight when there are
borders. Also border should be disabled. (non-regression)
