Comment:

 Seems like minor issues are fixed. Left over issues are complex ones and
 may be related to C bugs or improper C/TCL interaction. [[BR]]
 Steps to reproduce 5:


 nviz elevation=elevation.dem at PERMANENT [[BR]]
 Add new raster surface as constant ("New constant"->enter value 3000),
 uncheck "use as color"[[BR]]
 Click "DRAW CURRENT" -> new gray surface is displayed on top of
 elevation.dem surface (OK)[[BR]]
 Change new constant surface transparency, set it to constant (i.e.
 30)[[BR]]
 Click "DRAW CURRENT" once -> new surface gets transparent (OK)[[BR]]
 Click "DRAW CURRENT" for second time -> new surface is not transparent
 anymore (BUG)[[BR]]
 Click "CLEAR" and then "DRAW" -> new surface is displayed below
 elevation.dem (BUG)[[BR]]
 Click "CLEAR" and then "DRAW CURRENT" -> only new raster surface is
 displayed. elevation.dem is missing (WTF?)[[BR]]
 Change view and then click "DRAW CURRENT" -> new surface is transparent
 and on top of elevation.dem(OK)
