+/* GLUT Capture Sample
+
+   Uses GLUT for user interface
+        OpenGL for drawing
+        IM for image I/O and capture
+
+  Needs "glut32.lib", "vfw32.lib", "strmiids.lib", 
+        "im.lib", "im_capture.lib", "im_avi.lib" and "im_process.lib".
+
+   Control Keys:
+
+  <Esc> - Terminates
+  <Space> - Activates/Deactivates the capturing.
+  <F1>, <F2> , <F3>, etc - Shows capture configuration dialogs, in general 2, but can have more.
+  <v> - Starts to save every frame in an AVI file.
+  <b> - Process a background image using an average of N frames.
+  <s> - Saves the background image in a BMP file.
+  <1>, <2>, etc - Activates an processing operation. 
+                  Only operation 1 is working, it subtracts the background image if one was created.
+  <0> - Deactivates all the processing operations.
+
+  ATENTION: These keys works at the GLUT window. 
+            But the text input in done at the console window. 
+            Check the correct window focus before typing keys.
