<li>Updated modelist to include one more suggested mode for 800x600 resolution: Done by Andrew Bachmann;
<li>CRTC timing restriction checking updated: Modelists exported adhere to every cards max. CRTC capability now: the oldest cards support upto and including 1024x1000, while the newest cards support upto and including 1280x1024 resolution;

<li>Added full 2D acceleration for NM2097 and NM2160 cards (the others will be added later);
<li>Updated acceleration for massive speedup compared to Be driver (now running at approx 200-2000% depending on use!);
<li>Fixed acceleration on rectangle fills and inverts: nolonger executing zero-width commands (which the app_server gives to the driver sometimes!) so no more big-time distortion stripes onscreen! (the Be driver does exhibit this fault BTW);
<li>Updated hardware cursor to be placed elsewhere in cardRAM (acc engine requirement); distorted mousepointers could be fixed by this also on some cards outthere.
<li>Updated hardware cursor to be placed elsewhere in cardRAM (acc engine requirement); distorted mousepointers could be fixed by this also on some cards outthere;
<li>Updated workspace virtualsize restrictions for accelerated modes. Confirmed that the MagicGraph series (pre NM2200) engines can do upto and including 1600x1024 resolution. Assuming MagicMedia series (NM2200 and later) can do upto and including 1600x2048 for now. Modes above these resolutions are unaccelerated.
</ul>
Note:<br>
Acceleration engine benchmarked and tested for errors with BeRoMeter V1.2.6.
