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.
