The Mousetrap Library

About

libmousetrap is an LGPL'ed C library to create and manipulate mousetrap buffers in system memory. Mousetrap buffers are compressed two dimensional cartesian grids with integer precision. A mousetrap buffer retains an integer identifier for every point in the grid, so that later the identifier can be referenced with a set of (x, y) coordinates.

Why?

Well, when you're doing graphics programming and somebody clicks something with the mouse, all you get is the x and y location where the click was, and what mouse button they pressed. With the x and y location, all you can really get is the color of the pixel they clicked on, which doesn't tell you what *thing* on the screen they clicked on. There are lots of different ways to determine in your program what thing was clicked on, this library is one of them.
