add more sparkle

Figured something out recently that might helpful to know!

If you save your UV Snapshots out as a PNG, they are eligible to use Photoshop's FX features like Stroke and Gradient Overlay!

Using stroke (with it set as Center instead of the default of Outside) can allow you to control the thickness of your UV lines on the fly. 

Using gradient overlay with a rainbow texture lets you easily see where on your texture things are landing (if you're unsure), like the example above. It's less intrusive than using a cube-color map, and you don't have to toggle between them to see both. 

Ricockulous!
