Change all coordinate variables from "unsigned short" to "short".
Implement operations needed to draw lines and points in windows, to
determine the capabilities of the display, and to change the title bar
of a window. Extend the window-opening procedure to allow the window
style to be specified. Change PM primitives to allow multiple event
queues, so that messages for graphics windows can be kept separate
from messages for Edwin windows.

Add mechanism to "unread" messages back to the head of a message
queue. Add mechanism to get the other end of a qid pair. Eliminate
logic error that was being generated when sending a message to a qid
whose other end had been closed (now we just discard the message).
Reimplement message queues to NOT use the OS/2 queue abstraction --
apparently these queues use quite alot of memory and I recently ran
into a situation in which the memory was exhausted, which caused
Scheme to die. Now, the memory needed for the queues is taken from
the Scheme process's virtual memory.

Change implementation of readahead in input channels that require it.
Readahead is now buffered in the input queue by means of a new
operation to push a message back onto the head of the queue. Also,
there is now a mechanism to delay starting the readahead thread until
the first read occurs on the channel -- this is used for input pipes
that are passed to child processes and never read from the Scheme end.
It's important that such pipes not be read from.
