* Demo extrudeContourStepsMorphed which allows to create a mesh with a morphing cross-section

* Demo [extrudeContourStepsMorphed] which allows creating a mesh with an animated, morphing cross-section
* based on the t value along a [Path3D]. In other words, a tube in which the cross-section does not need
* to be constant, but can be scaled, rotated and displaced along its curved axis.
*
* Loads a texture and applies a repeat-wrapping mode to it.
* The texture can be enabled in the GLSL code inside
* the shadeStyle.
*
* The mesh is rendered 5 times rotated around axis Z
* for a radial-symmetry effect.
