I had an idea about how to place textured clips: use the selected area (with the cube selector) to get the x size and y size of the clip, as well as the x position and y position.
For example, if you wanted to create a 3x5 clip, you would select the area you want the clip to cover (and in the right location, too) and then use the textured clip command to give the rest of the arguments, i.e. /tclip [elevation] [height] [texture]
