<div>By 'completely replace' I hope you mean 'become the
default, but still be able to live alongside'. </div>

Maybe not even that. By 'completely replace' I mean stop using
BitBltCanvas and Engine in your image / application if you choose to
switch to the VectorCanvas and Engine.<br>
<br>
Ideally, the kernel image should be headless. Morphic should be an
installable package, requiring some pair of Canvas+Engine. It might
be BitBlt, Vector, OpenGL, Cairo or any other graphics backend we
might build. And maybe we can build a ST-80 style MVC as an
alternative to Morphic. People really wanting alternatives like
web-based GUIs, or native widgets should be able to build the
appropriate libraries and not be forced to have Morphic present if
that's what they want.<br>
<br>
Still, the default image might be BitBlt based... That's stuff we
need to discuss. It would be great to build the images we use (that
include dev tools) based on smaller ones. Or even a full bootstrap
from sources.<br>

<div>One of the things I've been hoping we end up with is a
more (wait for it...) modular drawing system. It would be
great to be able to switch between graphics systems and/or
have a worlds-like environment where the top level could be
one drawing system and one of the children another. </div>

<br>
Yep. Exactly.<br>

<br>
Well, that's actually sort of what I did. I renamed the existing
hierarchy as OldXXXMorph, built the new one, switched to it, and
deleted the old one. This was a looong time ago!<br>

<div>And then there are the low power/low capability devices
that don't even have full JIT support yet, let alone OpenCL
capable hardware. (lots of ARM stuff and some old/low-end

<br>
Of course. Although I'd love to be able to assume OpenCL is present
(not just for the graphics engine, but also for FloatArray and other
numerics and signal processing stuff), I know this is not the case.<br>
