annotate src/shape_rect.c @ 1381:9a585df24e52

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Consider the width and height attribute for the rect elements. The inkscape will change the width and height directly without using transform when we resize the rectangle.
