[Cuis-dev] Smalltalk on Android and in the Browser

[Juan Vuletich]

Hi Agustín,

I tested again after your recent updates.

VectorEnginePlugin works great on Android. I think this Makes Cuis a 
perfectly good platform for developing Android specific applications. 
This is big!!!

WRT SqueakJS, I can also confirm that it works OK now. 
VectorEnginePlugin also works, so now Morphic is pretty usable! Still, 
SqueakJS is (and has always been) much slower than the native COG VMs, 
so applications packaged as web apps using it will most likely be 
limited to rather simple UIs. Still, having Vector Graphics means that 
some kinds of applications, like complex visualizations can be done and 
will work well as long as they are mostly static.

Thanks so much for doing this!

Cheers,
