* VIEW.
* Holds a (potentially large) number of VIEW_ITEMs and renders them on a graphics device
* provided by the GAL. VIEWs can exist in two flavors:
* - dynamic - where items can be added, removed or changed anytime, intended for the main
* editing panel. Each VIEW_ITEM can be added to a single dynamic view.
* - static - where items are added once at the startup and are not linked with the VIEW.
* Foreseen for preview windows and printing.
* Items in a view are grouped in layers (not to be confused with Kicad's PCB layers). Each layer is
* identified by an integer number. Visibility and rendering order can be set individually for each
* of the layers. Future versions of the VIEW will also allows one to assign different layers to different
* rendering targets, which will be composited at the final stage by the GAL.
* The VIEW class also provides fast methods for finding all visible objects that are within a given
* rectangular area, useful for object selection/hit testing.
