screens into CPrimaryScreen and merged common code from secondary
screens into CSecondaryScreen. changed is-a relationship to a
has-a between the primary and secondary screen classes and the
generic platform dependent screen class to avoid multiple
inheritance of implementation. also standardized the interface
for those generic screen classes. adding a platform now involves
implementing simpler interfaces: IScreen for the generic screen,
IScreenEventHandler and some methods of CPrimaryScreen for the
primary screen, and IScreenEventHandler and some methods of
CSecondaryScreen for the secondary screen. did X11 platform
but not win32 platform.
minor changes to support IPrimaryReciever's functionality. this
does mean that the IPrimaryScreen class will be calling some
methods with dummy arguments. those are documented in
CPrimaryClient.
now speaks to the primary screen and secondary screens almost
everywhere the same way through an IClient interface; only
special primary screen calls are accessed through a different
interface, the CPrimaryClient interface. this simplifies the
server since it no longer needs to test whether the active screen
is the primary or a secondary in most cases.
the server no longer speaks directly to the primary screen; all
that goes through the CPrimaryClient, which often just forwards
the call. the primary screen no longer speaks directly to the
server either, again going through the CPrimaryClient via a
IPrimaryReceiver interface.
CServerProtocol classes have been replaced by CClientProxy
classes which are very similar. the name makes more sense
though.
