Render Brian Paul's classic OpenGL "gears" demo with TinyGL on a NuttX framebuffer device. TinyGL draws each frame into its own ZBuffer, which is then copied to the mmap()ed framebuffer (plus FBIO_UPDATE when CONFIG_FB_UPDATE is enabled), so partially drawn frames are never shown. The frame rate is printed every five seconds. Usage: tinygl [frames] [fbdev] Tested on sim:tinygl (640x480, 32 bpp): about 1400 FPS with CONFIG_DEBUG_FULLOPT on an x86_64 host, with both make and CMake.

(RGB32 or RGB565, see CONFIG_TINYGL_RENDER_BITS_*).
