	Name	Description
	GH_Viewport	Initializes a new instance of the GH_Viewport class
	GH_Viewport(GH_Viewport)	Initializes a new instance of the GH_Viewport class
	GH_Viewport(Point)	Initializes a new instance of the GH_Viewport class
	GH_Viewport(Point, Single)	Initializes a new instance of the GH_Viewport class

	Name	Description
	ControlMidPoint	Gets the point in the exact center of the viewport in control coordinates.
	Diagonal	Gets the length of the diagonal of the viewport in canvas coordinates.
	Height	Gets or sets the height of the viewport. Typically this is tied to the dimensions of the canvas. Height is not allowed to go below 5 pixels.
	MidPoint	Gets or sets the canvas coordinate that is directly underneath the center of the viewport.
	ScreenPort	Gets the dimensions of the viewport in control coordinates.
	Size	Gets or sets the size of the viewport. The size is typically tied to the dimensions of the Canvas.
	Target	Gets or sets the location of the target pixel. The target represents where the canvas origin is drawn.
	TargetRatio	Gets or sets the target ratio with respect to the viewport dimensions. This is a useful tool to prevent weird view changes during a canvas resize.
	Tx	Gets or sets the x-component of the target pixel. The target represents where the canvas origin is drawn.
	Ty	Gets or sets the y-component of the target pixel. The target represents where the canvas origin is drawn.
	VisibleRegion	Gets the rectangle in canvas coordinates that is visible in the control.
	Width	Gets or sets the width of the viewport. Typically this is tied to the dimensions of the canvas. Width is not allowed to go below 5 pixels.
	Zoom	Gets or sets the Zoom factor of the viewport. Please assign only sensible values.
	ZoomBoolean	Sets the zoom of the viewport with a view anchor.
	ZoomInverse	Gets the inverse of the zoom.

	Name	Description
	ApplyProjection	Apply the current display transformation to a Graphics object.
	ComputeProjection	Forces a recomputation of all cached data.
	DollyZoom	Advanced interface function for mouse 'dolly' zooming.
	Duplicate
	Focus(IGH_Attributes)	Look at a specific object.
	Focus(ListIGH_Attributes)	Look at a set of specific objects.
	Focus(Point)	Look at a specific point.
	Focus(PointF)	Look at a specific point.
	IsVisible(PointF, Single)	Test visibility of a point.
	IsVisible(RectangleF, Single)	Test visibility of a rectangle.
	LimitUnit	Utility function for calculating pixel dimensions in a zoom-aware environment. The desired value is put through the zoom projection and if the resulting size (as displayed on the screen) exceeds the visual limits it is clipped. This function can be used for example to make sure that a certain penwidth never exceeds visual limits (i.e. it doesn't get too thin or too thick on the screen).
	Project	Transform a point from canvas into control coordinate space.
	ProjectPoint	Project a point from canvas coordinates into control coordinates.
	ProjectRectangle	Project a rectangle from canvas coordinates into control coordinates.
	ProjectX	Project a value along constant X from canvas coordinates into control coordinates.
	ProjectY	Project a value along constant Y from canvas coordinates into control coordinates.
	Set
	SolveUnit	Utility function for calculating graphics dimensions in a zoom-aware environment. This function can be used for example to compute the linewidth of a pen which always needs to appear as 3 pixels thick on the screen regardless of zoom values.
	Unproject	Transform a point from control into canvas coordinate space.
	UnprojectPoint	Project a point from control coordinates into canvas coordinates.
	UnprojectRectangle	Project a rectangle from control coordinates into canvas coordinates.
	UnprojectX	Project a value along constant X from control coordinates into canvas coordinates.
	UnprojectY	Project a value along constant Y from control coordinates into canvas coordinates.
	XFormMatrix	Gets the display transformation cached by this viewport.
