+Description

+  GammaControl demonstrates how to use IDirectDrawGammaControl to adjust
+  how bright the system displays the DirectDraw surface.

+User's Guide
+============
+  Click the left mouse button to decrease the gamma ramp or the right mouse button
+  to increase it.  Press the ESC key to quit the program.
+
+Programming Notes
+=================
+  For details on how to setup a full-screen DirectDraw app, see the FullScreenMode 
+  sample. 
+  
+  To adjust the gamma, first check to see if the device supports it.  Call
+  IDirectDraw::GetCaps to check if DDCAPS2_PRIMARYGAMMA is set.  If it is, then
+  you can set the gamma ramp by calling IDirectDrawGammaControl::SetGammaRamp.  
+  
+  For simplicity this sample creates a gamma ramp which is linear for all 
+  color components.  The ramp runs from 0 at index 0 linearly up to a user 
+  defined number at index 255 for each of the color components.  However, the ramp 
+  does not need to be linear.
