Legend item to display vtkScalarsToColors.
vtkColorLegend is an item that will display the vtkScalarsToColors using a 1D texture, and a vtkAxis to show both the color and numerical range.

Bounds of the item, by default (0, 1, 0, 1) but it mainly depends on the range of the vtkScalarsToColors function.

Perform any updates to the item that may be necessary before rendering. The scene should take care of calling this on all items before their Paint function is invoked.

Paint the texture into a rectangle defined by the bounds. If MaskAboveCurve is true and a shape has been provided by a subclass, it draws the texture into the shape

Request the space the legend requires to be drawn. This is returned as a vtkRect4f, with the corner being the offset from Point, and the width/ height being the total width/height required by the axis. In order to ensure the numbers are correct, Update() should be called first.

Need to be reimplemented by subclasses, ComputeTexture() is called at paint time if the texture is not up to date compared to vtkColorLegend
