Service:
--------
1.6:
- increased speed of (long) annotation drawing
- add support for changing line thickness
- separated annotation drawing in one for transparent and one for opaque drawing,
   this prevents "circle-overlap" from occurring when drawing the two together
- fix bug where the dimensions of the PPT window would sometimes be calculated
   while the window moves, causing us to send only half of the window to the iPhone

1.5:
- parse launchd timeout to quit the service and release resources during periods
   of inactivity (launchd will resume it on-demand when needed)
- Fix owner name mismatch in CGWindow*() API that caused gray screen on some MBs
- login timeout support

1.4:
- Fix hangs in Service when PowerPoint quits while the iPhone app was connected
- Fix occasional iPhone display "hangs" (i.e. lack of updates from the Service as
   for display changes - until the next "activity") hangs under high "activity"
- Fix "Flickering" of Mac screen when first slide displays
- Fix failure of annotations to display on Mac, even though iPhone displays them
   fine (related to use of multiple Workspaces in "Expose & Spaces")
- Add a SIGTERM handler
- Fix "presenter mode" and "dual display" (non-mirror) mode detection

1.3:
- fix white screen on iphone if we started while ppt was on another Workspace
   (in Expose & Spaces)

1.2:
- workaround lack of location data in highlight call (for PPT Remote 1.0 compatibility)
- add laserpointer support (instead of arrowpointer)
- add laserpointer "highlight" function
- ensure that our detection of whether a presentation is running includes the fact that
   it might not be the frontmost process
- changed image encoding / comparing to be threaded such as to decrease pointer latency
- annotations are now drawn on a private "overhead sheet" surface instead of using powerpoint
- add short network timeouts to account for the iphone going into standby early and often

1.1:
- ipod touch support fixed

1.0:
- initial release

PPT Remote:
-----------
1.2:
- animations for "pop-up" screens etc.
- more / better error messages for connection aborts
- add highlighter to colorpicker (transparent, thicker line)
- allow changing line thickness and highlighter transparency in iPhone / iPod Touch
   Settings => PPT Remote

1.1:
- use no-delay tcp/ip flag for smoother mouse movement (arrow cursor/annotations)
- always close help/colorpicker dialogs when opening/closing presentation
- fix lack of location data in highlight call
- fix bug where 'next' button would become insensitive when closing the intro/help window
- added indicator icons for "next slide", "previous slide", "pointer" and "pointer highlight"
   gesture actions (as feedback, so the user sees what the device is doing)
- include support for responding to 'ping' commands
- include a version command to the wire protocol (bidirectional)
- read service version and give a notice if it needs to be updated
- improve touchable area of brightness bar and close/color buttons (make it easier to "hit")

1.0:
- initial release
