Eh?
One of the problems with being OCD about my LiveCode consumption is that
I can no longer recall where I hear things, whether it was in a
newsletter article, a blog post, or the Global Jam chats Kevin and Ben
hosted.
The IDE rewrite is AFAIK very early-stage, a logical necessity from the
Open Language initiative and the implications thereof related to
extensibility. I imagine we'll be hearing more about it as it begins to
move from sketchpad to code, but right now it's all about supporting OL
so I don't believe there's much concrete that can be said about it until
OL gets fleshed out more.
The rendering optimization has been ongoing for many builds, begun with
acceleratedRendering and tiling, and continued with the introduction of
Skia as the 2D graphics subsystem. Because Skia is layer-based, the
benefits of the tiling method are somewhat limited, so the team is
exploring a more with-the-Skia-grain approach of focusing on buffered
layers instead. I'm not familiar with the intricacies, but given that
so much of LiveCode's logic is layer-based I have to imagine this will
bode well as a more flexible approach over the long term.
Much of the initial rendering optimization was focused on the needs of
mobile platforms, but as Kevin reminds us most of the engine stuff for
mobile tends to benefit all platforms. Desktop apps are increasingly
using dynamic Metro-style layouts, and even now we can see significant
improvement with things like moving multiple objects simultaneously
(even on Linux, where rendering speeds used to be abysmal).
I don't know the specific status of the layer-based optimization (maybe
it's on those Global Jam chat videos), but I'm sure we'll be hearing
more about it as it gets further along, either in the daily blog posts
or the newsletter.
