In the image I just uploaded two days ago and that one can get
from <a class="moz-txt-link-freetext"

moz-do-not-send="true">http://www.zogotounga.net/comp/squeak/rogue.htm</a>
the main feature is a 2D real-time top-down game.
<br>
<br>
I found that the GC-caused jitter was indeed a problem, but also
that the main culprit was the time it takes to simply paint an
image which is a surprisingly (to me) slow operation.
<br>
<br>
That, plus the alpha-blending issue that was discussed on the VM
list a little ago, where Juan proposed two new primitives.

<p>Juan proposed these primitives to speed up the rendering of
VectorGraphics Widget Morph. <br>
</p>
<p>Regarding graphics, Juan's work on Vector Graphics can be of
interest for Squeak.<br>
