    README_DEMOS CONTENTS:
    	A simple fill-rate performance demo.  Automatically measures
    	fill-rate for different sizes and aspect ratios of triangles.
    	Prints data which can be displayed using "gnuplot."  See the
    	README file in application directory for more information.

    README CONTENTS:
    	This program prints data concerning the fill rate performance
    	for triangles of different areas and aspect ratios.  This data
    	can easily be plotted as a 3-D graph using gnuplot (see plot.gnu).

    	The program works by increasing the number of triangles until
    	a frame time is exceeded and then backing off slightly.
    	At this point, the fill rate is recorded and the next type
    	of triangle is drawn.  The triangles are drawn at random
    	locations, but within the 320x240 screen so that clipped
    	triangles are not a factor.

    	To define the extent of the graph, define the constants (in fill.h):
    		ASPECT_HI
    		ASPECT_LO
    		ASPECT_STEP

    		AREA_HI
    		AREA_LO
    		AREA_STEP
    	Note that only the RDP performance is measured.  There is a certain
    	amount of DRAM bandwith that is dedicated to loading the display
    	list into the input FIFO of the RDP.  To get the most accurate
    	answers, you should run with video blanked (-b option), and don't
    	do frame buffer clears (-c option).

    DESCRIPTION:
    	You should see an orange screen that is quickly covered
    	with yellow and black-speckeled triangles.  A green timer
    	bar will appear in the lower-left corner of the screen.
    	The timer bar will reset 50 times before the demo ends.
    	Each pass will also be displayed on the computer monitor.
    	The monitor will display the area, aspect, ntri per frame,
    	time per tri (usec), and fill (pix/sec)
