This example is found in ClanLib V2.2 SVN

It demonstrates that ClanLib can handle 3d textures.

The example create a mandelbrot image with 64 different depths - and smoothly transitions between the images.

This screenshot hows how OpenGL (via GL1 target) blends between planes (x,y,3) and (x,y,4)

Note: The GL target would require a GLSL shader to enable 3D Textures
