* Use GL vertex buffers and index buffers for 3D model rendering
* Use material or average vertex color for bounding boxes instead of red
* Reinstate bounding box rendering with GL vertex/index buffers
* Use compact vertex/index data representation
- 8-bit normals
- 8-bit colors
- 16-bit or 32-bit indices, depending on model size
This should improve performance a bit on lower end GPUs with less memory
and bandwidth.
Fixes#4112
Additionally, fix an unreported bug allowing zoom level to get stuck at
MAX_ZOOM.
Fixes: lp:1625754 (3dviewer zoom not limited with Use touchpad to pan)

* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
non-transformed S3DMODEL for rendering.
+ S3D_CACHE now caches S3DMODEL and returns a pointer to a single
instance of the S3DMODEL for repeated calls to Prepare()
+ Beginning the VRML Plugin
