[ALLY] getting the screen-size Re:(4)

how about "Virtual Coordinate Space" with automatic?
instead of
[layout/span/size face 4096x3072 341x25]
:
[view/fullscreen layout[stuff] ]
and the resize can be done pretty hidden..
there should be a simple wishing for resolution/colors
-preference for the scripter. header-option?
from /view - doc:
A virtual coordinate space makes it possible to develop a visual interface without needing
to know the actual display size.
This is to say, it makes it possible to use a virtual pixel space for aligning face objects.
So, the resolution of a user's display
does not need to be known before designing a visual interface. For instance, say you
want to create a visual interface that
will look the same between systems with a maximum resolution of 320x240 and systems with
resolutions of 1280x1024
and greater. This can be done with View's virtual coordinate space capabilities.
A window's virtual coordinates are defined in a window's top level face's span facet.
To set the span, use the /span and
/size refinements when using layout to display a new face. The /span will indicate the
virtual coordinate space while /size
specifies the actual pixel size of the window.
