[sldev] P2P/Squid Web Textures: Enabling Greater Quality Images - draft 2

[Dzonatas]

I just backed-out of thinking-out the "patched" sculpties with a 
specialized tile method on the DWT. Right now the alpha layer is not 
being used, and it could easily be used to create arbitrary sized sculpt 
patches. It may be hard to compute on the physics side, but it occurred 
to me that the SLSquid idea allows sculpties of even 1024x1024 
detail.... or greater!

No server side changes needed. Just drop the UUID that a SLSquid server 
returns, when you upload it to the SLSquid-mesh, into the prim (set it 
by LSL).

Highly detailed sculpties. Laggy? Nah... not with the OpenJPEG and LLV4 
changes.

Well... its just a dream for now. =)
