FTGL Fonts starting to work.
FTGL is working for all text drawing.
Use CMake FindPackage to find FreeType include directory and libraries.  Add FTGL font rendering to wb_command -show-scene.  Got new FTGL system to compile on Linux.  Enable compilation of Workbench when FreeType library is not available.
Removed GLF Font System
Cleaned up BrainOpenGLTextRenderInterface.  Made updates to the QT text renderer.  Change FTGL text rendrerer to read the font files from resources.  Added font files to resources.
Added a 'dummy' text renderer that is used when a valid text renderer is not available.  Typically this occurs if a FreeType library is not available when compiling.
Added the FTGL license and other files to FtglFont module.
Added the FTGL license and other files to FtglFont module.
Fixed compilation warnings caused by unused variables in FTGL Font library.
Add a name for the text renderer and display this name in the OpenGL configuration information available through File (Apple) Menu -> About wb_view -> OpenGL.
Added search path for FreeType
More updates for help files
Add setting of FreeType directory for windows build environment.
