Etymology
X11PCDLColoredPoints : X11PixelCanvas
Synopsis
This class is designed for use with the
X11PixelCanvas'
caching mechanism.
Cached version of the X11PixelCanvas
drawColoredPoints() function which stores point and color information
in native X structures for later recall.
Motivation
Needed to be able to put all output graphics commands in
a display list for fast and convenient handling.
