Log Message:
-----------
Howard Hoagland. Made changes to 4 classes (PclRenderImage, PriDrawText, OpenPCLViewer, IPluginHooksOpenPCL) to implement this new feature: If the user Control-Clicks the toolbar "Options" button, then toggle show/hide to see white text hidden tag strings on the screen by redrawing the white text in dark green. Also draw a dark green box around the now visible txt.
