+New features in GLUT
+--------------------
+
+1. Frames per second printing
+
+ GLUT now looks for an environment variable called "GLUT_FPS". If it's
+ set, GLUT will print out a frames/second statistic to stderr when
+ glutSwapBuffers() is called. By default, frames/second is computed
+ and displayed once every 5 seconds. You can specify a different
+ interval (in milliseconds) when you set the env var. For example
+ 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval
+ to one second.
+
+ NOTE: the demo or application must call the glutInit() function for
+ this to work. Otherwise, the env var will be ignored.
+
+ Finally, this feature may not be reliable in multi-window programs.
+
+
+2. glutGetProcAddress() function
+
+ The new function:
+
+ void *glutGetProcAddress(const char *procName)
+
+ is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It
+ lets you dynamically get the address of an OpenGL function at runtime.
+ The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the
+ GLUT version number from 3.7 since that's probably Mark Kilgard's role.
+
+ This function should probably also be able to return the address of
+ GLUT functions themselves, but it doesn't do that yet.
+
