NAME
     glutGet -- Allows you to query some general state/option variables.

LIBRARY
     OpenGLUT - state

SYNOPSIS
     #include <openglut.h>

     int
     glutGet(GLenum eWhat);

PARAMETERS
      eWhat	Enumerated parameter ID.

DESCRIPTION
     This function permits you to query for the current value of many different OpenGLUT state variables.  The current list is:

      -  GLUT_ACTION_ON_WINDOW_CLOSE
     Allows you to do something other than die if the user closes one of your windows.

      -  GLUT_DISPLAY_MODE_POSSIBLE

      -  GLUT_ELAPSED_TIME

      -  GLUT_INIT_DISPLAY_MODE

      -  GLUT_INIT_STATE

      -  GLUT_INIT_WINDOW_HEIGHT

      -  GLUT_INIT_WINDOW_WIDTH

      -  GLUT_INIT_WINDOW_X

      -  GLUT_INIT_WINDOW_Y

      -  GLUT_MENU_NUM_ITEMS

      -  GLUT_RENDERING_CONTEXT
     Allows you to specify context-sharing when you open new windows.

      -  GLUT_SCREEN_HEIGHT

      -  GLUT_SCREEN_HEIGHT_MM
     Height in millimeters.

      -  GLUT_SCREEN_WIDTH

      -  GLUT_SCREEN_WIDTH_MM
     Width in millimeters.

      -  GLUT_VERSION

      -  GLUT_WINDOW_ACCUM_ALPHA_SIZE

      -  GLUT_WINDOW_ACCUM_BLUE_SIZE

      -  GLUT_WINDOW_ACCUM_GREEN_SIZE

      -  GLUT_WINDOW_ACCUM_RED_SIZE

      -  GLUT_WINDOW_ALPHA_SIZE

      -  GLUT_WINDOW_BLUE_SIZE

      -  GLUT_WINDOW_BORDER_WIDTH

      -  GLUT_WINDOW_BUFFER_SIZE

      -  GLUT_WINDOW_COLORMAP_SIZE

      -  GLUT_WINDOW_CURSOR

      -  GLUT_WINDOW_DEPTH_SIZE

      -  GLUT_WINDOW_DOUBLEBUFFER

      -  GLUT_WINDOW_FORMAT_ID
     System dependant.

      -  GLUT_WINDOW_GREEN_SIZE

      -  GLUT_WINDOW_HEADER_HEIGHT

      -  GLUT_WINDOW_HEIGHT

      -  GLUT_WINDOW_NUM_CHILDREN

      -  GLUT_WINDOW_NUM_SAMPLES

      -  GLUT_WINDOW_PARENT

      -  GLUT_WINDOW_RED_SIZE

      -  GLUT_WINDOW_RGBA

      -  GLUT_WINDOW_STENCIL_SIZE

      -  GLUT_WINDOW_STEREO

      -  GLUT_WINDOW_WIDTH

      -  GLUT_WINDOW_X

      -  GLUT_WINDOW_Y

     Most of the above are very obvious, and so full documentation is postponed for now.

TODO
     Go back and flesh out the above list.

     This function is a bit messy, especially the WINCE part.  Fix.

     Lots of code uses return to hop out.  Since it's such a sprawling function, it's easy to be in the middle and not be 100% sure if there's
     anything important at the end of the function, or if it is safe to just "drop out" of the current case and head for the bottom.

     Causes crashes (assertion failure) if you call this before having called glutInit()---other than GLUT_INIT_STATE and GLUT_ELAPSED_TIME.
     Because various things can cause OpenGLUT to become deinitialized, we should probably either return default values of some kind or do minimal
     initialization if we are called without proper initialization.
