the re-regsitration is a "send" not a "lend" now, because
the imef can't block during the context switch.
Not sure why I made it a lend in the first place, probably just
wasn't thinking...
only cone connection is allowed to the IMEF anyways, because
the GAM does traffic control on who has authorization to access it.
So, no need for multi-callback support. Saves a tiny bit of RAM.
request_focus is "dangerous" because any random server could
request a UX context to pop up. There is a checked version
that requires a GAM token that should be used, but, this leaves
the question of how does the initial app that's supposed to be
focused gets set.
A small mod to the UxRegistration call is made to check for
the name of the default focus app, and when it is seen, a thread
is fired off to request focus for that app. That allows us
to deprecate this otherwise dangerous call.
trust levels now default to a mid-level, with the password
modals explicitly tested for by the Context logic (the idea
being to deny any untrusted canvases the ability to render
inverted text).
ball bounce app also basically works, and context
switching between the bounce app and the main menu
is working too.
The first "app" is just going to be a whole-framebuffer
demo that gets raw keys and does some stuff on the screen.
It's the starting point if you wanted to eg. write a simple
video game or something for the device, but you didn't care
about much of the other UX sugar.
Really clear up the roles and structures of word wrapping.
Significantly, we have now figured out that the word wrapper
should be the word wrapper, and that the text bounds should
be computed by a text bounds computation.
Conflating flexible text bounds with word wrapping makes
the math really hard.
So, the word wrapper always works with a bounding area starting
at 0,0, and will wrap until it hits a Point designated as its
absolute max bounds.
The returned typeset block is referenced to 0,0, and then it
is shifted to the correct location by the rendering function.
This externalizes the computation of the final location plus
the rendering bounds to the outer functions that need to care
about this, thus simplifying the word wrapper significantly.
