nanogui: Thread: [Nano-X] GrNewPolygonRegion

Dear All,

	Based on Greg's new patch for clipping regions,
	I've added the new function:
GR_REGION_ID    GrNewPolygonRegion(int mode, GR_COUNT count, GR_POINT *points);

	But the function is still buggy.
	I tried to trace the bug, and found it seems to lie in the function
	REGION_InsertionSort.

With regards,
Murphy

I've added all this into the source tree.  There were a couple of
problems.  One, the function wasn't added into the Wrapper
list in srvnet.c.

Now polygon regions work fine if the application is linked with
the server.  Otherwise, the GR_POINT values are corrupted when
sent from client to server and the server dies.  I should have this debugged
shortly.  (The nxproto.h states that variable size client/server packets
must be handed padded; I added this but it's still broken)

It's working now.  The problem was that the NewPolygonRegion
request packet wasn't hand-padded to a 4 byte boundary.  This
is required to ensure that the variable length data starts on a 4 byte 
boundary, for alignment reasons.

I've been busy adding the many contributions, and am planning
another cut shortly.  (we now have arcs, pies, outlined arcs, as
well as a listbox, edit and progress bar for win32, as well as
arcs, pies, regions and a window manager for nano-X.)

Regards,

Greg
