| * This browser doesn't handle well using the cropping abilities of drawImage | |
| * with out-of-bounds values. | |
| * (see https://stackoverflow.com/questions/35500999/cropping-with-drawimage-not-working-in-safari) | |
| * This script takes care of detecting when the monkey-patch is needed, | |
| * and does redefine the cropping parameters so they fall inside the source's boundaries. |
