GRASS 7: NVIZ: Transparency error for constant surface in

Description
Hi,
I notice that setting the constant surface transparency to any value other that zero, causes the constant surface to disappear above a raster layer. The surface remains visible surrounding the image. Only if the constant surface is given a transparency of zero (i.e., 100% opaque) is it possible to position above a raster image.

see also #2175, since it is also seen from the command line with m.nviz.image, the root cause seems to be in the ogsf library functions.
what happens is the transparent planar surface is rendered first, then the DEM is rendered over the top of it, instead of the DEM being rendered first then the the transparent planar surface rendered through it.
Similar behaviour is also seen for #2175 in devbr6, and perhaps 6.4 too (untested).
