gl slider - (for Tripp & Kurt)
Here's a patch that implements a horizontal slider inside of a jit.gl.render. It got a bit complicated because jitter doesn't provide any simple method to translate from screen to 3D space.
A few caveats: You can move the camera along the z axis, but it breaks if you change any other camera parameters. And it keeps working when you change the size of the window with a "size" message - but you have to keep to a 4 x 3 ratio. The esc key toggles "full screen" (keeping to the 4 x 3 ratio). If something doesn't update when you change it, just click on the window & it should pop into place.
There's a toggle to turn on and off the mouse y coordinates (default off), and when it's off you can change the y position of the slider. And there's a separate control for setting the active vertical region of the screen.
It should be (relatively) easy to add a second slider (by distinguishing between two different ranges of mouse y coordinates) - but if you're having trouble let me know. Likewise any questions.
