class Drawer from Prs3d inherits TShared from MMgt
---Purpose: A graphic attribute manager which governs how
-- objects such as color, width, line thickness and
-- deflection are displayed.
-- Prs3d_Drawer is the mother class of AIS_Drawer.
-- As such, it is its set functions which are called to
-- modify display parameters. In the example below we
-- can see that the AIS_Drawer is modified to set the
-- value of the deviation coefficient using a method
-- inherited from Prs3d_Drawer.
