Bug Description
When exporting to PNG and setting 'dpi' to 0 and any pixel sizes to a non zero value (i.e. constraining the size of output image), no image is produced.
The following message is issued ont the console:
gd warning: one parameter to a memory allocation multiplication is negative or zero, failing operation gracefully
and this one to the application log:
png_do_export(): gdImageCreate(256, -41) returned NULL. Aborting export.
The negative value passed to gdImageCreate() is the result of an overflow of the (32 bits) Coord variable used for computing the size of the image.
