the trailing update after every event seems redundant now that
the gam is cleaned up
also fix a bug that causes overflow text on tl fitted text
to overflow the drawing region
the problem is that during the computation of the lines, the
cursor isn't wrapping to the next line if the last character
would render "into" the edge of the box. adding a trailing
space to any incoming strings forces the line to wrap.
you can aggravate this condition by typing the following
sentence into the shell:
this is a test of a message that is too long a message
when it fails, it renders
this is a test of a messag
e that is too long a messag
adding the trailing space causes it to render as
this is a test of a messag
e that is too long a messa
ge
which is the desired behavior
The fps limiter ends up blocking the whole system due to how it limits
the framerate.
If we want to put in a proper rate limiter, we should move the Server
into a different thread and keep just the framebuffer on the main
thread.

this ensures that "all back" dialog boxes that are fake
are also defaced (as opposed to just drawing black, which
would not deface a "fake" dialog box).
right character gets cut off, but it's because the cursor is
the top left of the last character. add one character height plus
margin to the shortening, because the margin itself could be 0
in many case.
Mark the private fields in a `MemoryRange` struct as being private. This
allows us to perform operations on the memory range armed with the
knowledge that the entire range is valid and unaliased.

this prevents less trusted processes from connecting to servers
after the kernel initializations are done.
this works so long as we don't have disconnects from the kernel
servers. In order to support disconnects we will also need a
way to re-enumerate the SID to guarantee that we don't have a re-use
problem. But for now, the kernel is not designed with any practical
disconnect mechanism; there is no code that calls the Quit mechanism
on any server.
- inverted text indicates a trusted message. policy is enforced in the GAM.
- we don't have a way to lock the USB port yet; but at least now it's communicated.
the connection number is re-used for all objects created
within a process space, so you can't `Drop` the connection
immediately when an object goes out of scope. You have to
make sure all instance of the object go out of scope. This
patch adds reference counting to all the objects so that
the `Drop` function works as intended.
