GUI library

The GUI library provides a general GUI object and a set of elements to design and operate a human machine interface.

It manages touch and haptic feed-back as well.

Danger

Because the GUI library uses fast and partial updates, it requires one of the PDLS_EXT3_Advanced_Fast_Large, PDLS_EXT3_Advanced_Fast_Medium, PDLS_EXT3_Advanced_Fast_Small and PDLS_EXT3_Advanced_Fast_Touch libraries.

Some elements use items, a structure that combines an index and a label.
