The first order of business of an EZwgl application is to initialize the EZwgl library. This is achieved by calling
EZ_Initialize(int argc, char **argv, int initGL);
or
EZ_InitializeXrm(char *className, XrmOptionDescRec *optsTable, int noptions, int *argc_in_out, char **argv_in_out, char *fallbackResrc, int initgl);
These two functions parse the command line arguments, opens the X server connection and initialize the internal data structure for EZwgl.
