Imagemagick to create favicon.ico with 16x16 and 32x32 sizes in it
# IE is still braindead so still use favicon.ico
convert -resize x16 -gravity center -crop 16x16+0+0 -flatten -colors 256 input.png output-16x16.ico
convert -resize x32 -gravity center -crop 32x32+0+0 -flatten -colors 256 input.png output-32x32.ico
convert output-16x16.ico output-32x32.ico favicon.ico
# Then, HTML needs to specify size="XxY" as largest size due to browser bugs
<link rel="shortcut icon" href="/favicon.ico" sizes="32x32">
