The current portable build script is getting messy and unnecessarily complex. We should separate the Linux build of portable out of the python script and into our Scons build scripts. The portable python build script then would be dedicated to windows.

To Reproduce

See the portable build script.

Expected behavior

Portable for Windows is built with the dedicate python script a

When converting a GridMap to an OpenCV image with the method grid_map:GridMapCvConverter::toImage, the cv::Mat is initialized with zeros (black pixels) (here) then, only finite values are copied from the GridMap to the cv::Mat ([here](https://github

@chris-little's feedback from CesiumGS/3d-tiles#405:

Can tilesets be nested hierarchically? I'm not sure from the text.
Can a tile can be "in" more than one tileset? I'm not sure how, but presumbly URIs allow this.

The answers are "yes" and "yes" but they could be clarified in the reference card.

Additional Information

Encountered in e.g. the Cube example and TacticalSymbol class. Notably, also found in README.md. Such references should be substituted for current ones.

Could you add some user documentation to the wiki? I built Mundus from the Git repo, downloaded the MundusDemo project from the other Github project, but all I could figure out how to do was move the camera XYZ with the QWEASD keys. I installed (and tested) fbx-conv and pointed to it in Mundus settings, but still all OBJ imports failed, advising to pick the right file and set the right fbx-conv. C

Description:

Repro steps:

1. Target cursor on a “Apply” button
   Expected: Tips must have space with button
