// comment: This visual program illustrates the use of Texture Mapping. 
// comment: 
// comment: IMPORTANT: Texture mapping is available only with a hardware card which supports it. OpenGL and some versions of GL support texture mapping. (If you are using an ibm risc system/6000 machine, you may want to check README_ibm6000 to ensure that OpenGL is enabled, if available.) This visual program is set to use hardware rendering by default.  Depending on your machine, if you run this visual program and *do not* have a hardware card, DX may abruptly terminate.
// comment: 
// comment: An image (in this example, the DX logo) is texture mapped onto a much lower resolution height map. To the height map is added a "uv" component, which specifies how the image should be mapped to the geometry. Each component of uv goes from 0 to 1.
// comment: 
// comment: Go into execute-on-change mode and rotate the object to see the effect of the texture mapped height field.
// workspace: width = 453, height = 615
// layout: snap = 0, width = 50, height = 50, align = UL
