[Bug 1473523] [NEW] convert exports SVG ignoring -size parameter

[John Drinkwater]

Public bug reported:

Ran into this bug on a new 15.04 install, asking convert to output a PNG of a specific size from an SVG, it would always output in another fixed size.
It seems to be caused because now imagemagick is not built with rsvg support.

Running -verbose shows that ghostscript is being run with -g1024x576
which is ignoring the passed in setting:
