* <p>This helper method is used in the "initializeAppearance" methods below to set up the shaders

* (not doing this has created odd bugs in the past).
*
* <p>We set whether edges and vertices are drawn elsewhere (in View.java). In the past, we've
* found that trying to use the "Appearance.setAttribute(CommonAttributes.*)" method of setting
* attributes and setting this properties on a shader (Ex. dgs.setDrawLines(false);) leads to
* problems. Thus, we don't specify whether edges/vertices should be drawn in the properties
* below. *******************************************************************************
