This texture comes in handy when you want to align things to a grid.

Recently, I had the need to turn a hundred different texture images into "profiles." A profile, in this case, was a 2D shape that follows the outline of some feature in the texture (like a house facade), texture mapped with that feature. Rather than build them all in a modeler such as 3ds Max, and separately exporting them, I came up with a simple tool for loading a bunch of images, building those profiles straight on a copy of the image using clicking, saving all the profiles I've built (for later re-use or editing), and exporting to a bunch of .DAE (collada) or .X files in one fell swoop.
