## SVG2PNG: Each is buggy in their own way
## Usage: $(call SVG2PNG,infile,outfile[,width,height,background-color])
##
## ImageMagick: doesn't support transparency
#SVG2PNG = convert $1 -format png $(if $3,-resize $3x)$(if $4,$4) $(if $5,-background $5) $2
## librsvg: doesn't support <style> element
#SVG2PNG = rsvg-convert $1 -o $2 $(if $3,-w $3) $(if $4,-h $4) $(if $5,--background-color=$5)
## Inkscape: messes up gradients
SVG2PNG = inkscape $1 --export-png $2 $(if $3,-w $3) $(if $4,-h $4) $(if $5,-b '$5')

#PNGCRUSH = cp $1 $2
PNGCRUSH = pngcrush $1 $2
