C2D2_Canvas_Wrapping_or_Utilities.js

// Using only direct canvas method wrappers (which use the same
// name as official canvas methods):
ctx.shadowColor('green').shadowBlur(2).shadowOffsetX(5).shadowOffsetY(10);

// Using one utility method (at the end) amongst direct canvas method wrappers:
ctx.shadowColor('green').shadowBlur(2).$shadowOffset(5, 10);

// Using custom utility exclusively with its own simplified
// non-canvas (but easily derived) syntax:
ctx.$shadow({color:'green', blur:2, offset:[5, 10]});
