Changes in CAVE Library Version 2.4.2

• Added new navigation functions - CAVENavTranslate(), CAVENavRot(), & CAVENavScale(). The functions maintain a transformation matrix in shared memory, which is loaded at the beginning of each frame before application functions are called. Related functions are CAVENavLoadIdentity(), and CAVENavConvertCAVEToWorld() & CAVENavConvertWorldToCAVE() for converting positions between coordinate systems.
• Added tracking & display support for BOOM. BOOM tracking is selected by "TrackerType boom"; display is selected by using the "dual_eye" wall.
• Added updated Polhemus tracking.
• Added CAVEDisplayBarrier() function, which can be used to synchronize all the display processes.
• Added CAVEResetTracker() function.
• Corrected stereo projection for simulator display mode. Added SimulatorView configuration option for defining the simulator display viewing frustum.
• "Simulator1" wall is a simulator view that is always in mode 1. "Simulator2" wall always remains in mode 2.
• Added support for windowed Immersadesk display. Frustum will be calculated based on position & size of window on screen (DeskCorners should define geometry of entire screen). (IrisGL only)
• Improved parsing of pipe number in WallDisplay configuration option. Previously, a pipe of ":1" or ":2" would not have worked correctly.
• Changed order of display loop so that the InitApplication function is always called first in a frame, rather than after the FrameFunction.
