VB6 Cairo-Blending-Performance (Collision-Handling using the Physics-Engine)

A small Demo, referring to the Blending-comparison-thread here:
http://www.vbforums.com/showthread.p...-Cairo-Drawing

Now covering a more realistic "2D-game-scenario" with 12 moving PNG-Sprites (5 larger and 7 smaller ones),
which constantly change their Pixel-Contents whilst moving around on a more realistic gaming-surface-size
in the range of 1024x768 Pixels (each Sprite also updating itself with a Text-Rendering, showing the Collision-
Count it encountered so far).

What Cairo achieves with that amount of semitransparently rendered Sprites is about 250FPS
(measured on Win 8.1, on a 2.1GHz Intel-Mobile-CPU, singlethreaded) - whilst codewise consisting
of only about 40 lines in cBall.cls and about 60 lines of code in fTest.frm.

So the measured 250FPS in this scenario leave enough room for a lot more Sprites in the Game-Loop
(especially when those Sprites are not as large as the ones I've choosen here).

I consider that quite a good compromise between "convenient coding of complex graphics-stuff" -
and achievable 2D-game-performance.
