Initial exploration of drawElements()-based hide()

[aothms]

Started looking into hiding elements by ranges to drawElements() nothing worth looking at yet.

Things are starting to get a bit more complete now. There is some sort of selection and element hide working.

Select with left mouse button, press [h] to hide selection

Open issues:

• element hiding does not affect pick render call yet (so you pick hidden elements)
• fat line rendering does not work with quantization yet (so turn of all quantization related settings)
• propably more

Note, the assumption is that few elements are hidden and or selected. Performance will degrade with many elements selected and or hidden.
