Orbiter release 031217
======================
This is a minor update from 031105 containing mainly bug fixes and a few new
features.

Change log 031105 -> 031217
---------------------------
* Bug fix: Planet textures are now restored in T&L fullscreen modes
  after Alt+Tab.
* Bug fix: PlanetPatchRes entry in Orbiter.cfg is now interpreted correctly
  (higher planet texture resolution for entries > 1)
* New feature: Option to ignore joystick throttle setting on simulation
  start has been added to Joystick tab in Orbiter Launchpad.
* Modified colours for specular reflection from water surfaces
* New feature: Added "cloud shadows on surface" visual option
* Docking port index for direct HUD selection (Ctrl+Alt+R) now starts with 1
  (previously 0) to make consistent with dock numbering in info sheet (Ctrl-I)
* Direct target selection for Docking MFD (Shift-T) now works with vessels (not
  just legacy stations) and allows docking port specification
* Docking MFD now stores mode (NAV/VIS) and slaved NAV receiver index.
* Reduced SIZE parameter in Canaveral.cfg to 1000 to avoid rendering of surface
  tiles at large distances.
* DG exhaust particles now defined for both main engines separately. Single-
  engine situations are now handled properly.
* Bug fix: Shuttle-A auxiliary pod rotation animation error.
* Modified profile drag calculation for DG with more pronounced drag increase for
  high AOA.
* Bug fix: Base tiles can now be applied on the southern hemisphere. Note that:
  (a) latitude index 0 in the base config file (and tile texture name *_n0000.dds)
      correspond to tiles immediately north of the equator, while latitude index -1
      (and tile texture name *_s0001.dds) correspond to tiles immediately south of
      the equator.
  (b) textures for tiles on the southern hemisphere must be rotated 180 degrees.
* Bug fix: Pixelated edge in horizon haze textures with FSAA.
* New feature: F9 now also displays ecliptic grid and equator of target planet on
  celestial sphere, plus planet and vessel markers. New "Planetarium options"
  dialog (Ctrl-F9).
* Celestial bodies (planets, moons) are now rendered at larger camera distances as
  pixel blocks with variable intensity.
* Polar regions can now be covered with level 9 texture patches.
* The display of the info block in the top right corner can now toggled with "I"
  also in internal (cockpit) view. The info block has been cleaned up a bit.
* New categories "Celestial body" and "Camera target" added to object info dialog
  (Ctrl-I). Planetary orbital elements and positions are no longer displayed in the
  main simulation window.
* "Planetary texture files" documentation has been moved from User Manual
  (Orbiter.pdf) to API Guide (Orbitersdk\doc\API_Guide.pdf).
* The "step limit" entry in the orbit stabilisation definition of the orbiter
  launchpad is now active. This value is interpreted as follows:
	Only apply orbit stabilisation if this condition is satisfied
	(in addition to all other conditions):
		v dt > a 2pi r
	where v: orbital velocity, dt: time step, a: step limit,
	r: radius vector length
* Upgraded Orbiter's star database (star.bin) to Hipparcos data set (>100000
  stars). The lauchpad now contains a "Contrast" entry in addition to "Brightness"
  to control the appearence of stars. The "Constellation colour" entry has been
  removed.
* SDK: oapiOpenInputBox: input boxes now accept all printable characters as input.
* Vessel thrust ratings (main, retro, hover) are now listed in the info sheet
  (previously in the simulation window).
* Orbiter now again assigns keys 1,2..0 for plugin MFD modes which request a
  selection key that is already assigned.
* Bug fix: possible crash on repeated opening of input box fixed.
* Bug fix: fixed problem that caused FlightData dialog not to update its graphs.
* Reference planet for Surface MFD and atmospheric calculation now based on
  distance to planet surface rather than centre.
* Added the latest version (v3.05) of Duncan Sharpe's TransX MFD module.
* Bug fix: initial field of view (FOV) is now correctly read from scenario.
* Shuttle-PB: Now contains RCS thrusters for forward/back motion in linear mode.
* Shuttle-PB: Particle streams for main and hover thrusters.
* Mouse wheel is now supported to move the camera towards/away from the target
  in external views (replicating PgUp/PgDown)
* Global surface base velocities are now correctly updated.
