Add option to include bleed or document better

[sffc]

The Game Crafter requires images with resolution 825x1125 which appears to be 2.75x3.75 inches at 300 dpi, including 1/8 inches of bleed on all edges.

This can be modeled in Card Creatr Studio with the following advanced configurations:

	viewports: {
		card: {
			width: 198
			height: 270
			xOffset: -9
			yOffset: -9
		}
	}
	dimensions: {
		card: {
			// 2.75 in by 3.75 in
			unit: "pt"
			width: 825
			height: 1125
			dpi: 72
		}
	}

This can be applied to any existing poker size card template without having to modify the template.
