Some Shapes don't render in the CreateSampleShape GUI

[Keith Brown]

There are some shapes in the CreateSampleShape GUI that won't render either on their own or as part of an operation.

The affected shapes are: Hexahedron Cylinder Ring Slice Cone

Hexahedrons and Cones should render and they're useful in samples and should be fixed by this ticket.

Cylinder Ring Slices aren't as useful in samples, but if they're fixed by fixing Hexahedrons and Cones, great, however if they would require specific extra work in order to get them to render, they should actually be considered to be removed as an option in the CreateSampleShape GUI as they're unlikely to be used in samples

Looking for cause of non-render

Currently breakpointing the suspect area.

Found out that the culprit for the cone is most likely because the bounding box is returning wrongly.

Added .h files to cmake list

All the primitive shape's .h files were missing from cmake. Added them even though it does nothing functionally

Tidied up some code after my attepts to find the cause

The cause of the Cone not rendering is that it's bounding box isn't calculated and it just returns the bounds given to it. So it is actually rendering, it's jsut so small not even a pixel is small enough to represent it.

As calculating this is beyond my skill i'm going to have to leave this ticket to someone else, so i've fixed the code i'd altered in my search for the problem and tidied some other areas.
