terrain heights up to 508 are possible on the LL grid (and were available on previous releases of OpenSimulator).
The obvious way to allow both this and equivalent -z values, is to rewiden the internal terrain height storage from short to int.
The memory tradeoff is most noticeable on the maximum 8192x8192 var region (equiv to 1024 normal regions), where it adds 128mb to resident use (128k on a normal region)
This is still better than the double used in previous releases.
This does not affect physics or data storage since they already use float and double respectively.
This may not be the final solution if we actually want to sacrifice -z, >327 or something else.

This uses an offset of 0.05 on the up vector of the sit orientation, after extensive analysis on
http://opensimulator.org/mantis/view.php?id=7096 and https://wiki.secondlife.com/wiki/Talk:LlSitTarget
This supersedes the previous adjustment in 5b73b9c4 which had been wrongly applied.
The maximum change is about 0.1 with a maximum height avatar.
This patch is all Aleric's work - I am applying manually in order to add these additional notes
objects in the world.
This was originally changed in an attempt to make vehicles work better
but the effect was not that large and it causes avatars to float
above the terrain.
When an avatar is in their home grid, their name appears as "First Last". In other grids the name appears as "First.Last @grid.example.com". However, viewers have a bug and they don't always show the new name. We use a trick (changing the Group Title briefly) in order to make the viewers show the new name. This is only done after a Hypergrid teleport.
to the physics engine.
This operation was accidentally removed while in the middle of improving
the computation of the avatar height. This is a temp fix until the real
solution is added.
Also fixes an issue where sitting avatar counts became inaccurate after any cross.
Part of the problem was due to cloning code using MemberwiseClone() but not resetting certain collection structures.
Adds regression test for this case.
In relation to http://opensimulator.org/mantis/view.php?id=7050
Root cause was that PrimLimitsModule was not properly handling the case where the parcel it was asked to check was outside the current region's bounds.
If this is the case, we can abort the check since the receiving region will perform it.
Added a regression test for this case.
Recent versions of Firestorm and Singularity have started sending the viewer name in the 'Channel' field, leaving only their version number in the 'Viewer' field. So we need to search both of these fields for the viewer name.
This resolves http://opensimulator.org/mantis/view.php?id=6952
It does not indicate that a SOG has been set to be backed up or not. It indicates that a SOG can be backed up in principle.
In practice, this was added by lbsa71 in 2007 and is set to always true, albeit as a virtual property.
This is because xmlrpcgroups currently always checks visibility for the requesting agent ID (unlike Groups v2, which can accept UUID.Zero)
But group notice IMs have a from agent which is the group rather than the sending agent.

than everytime terrain is changed.
The TerrainModule now hooks the frame event and, if terrain has changed,
sends terrain updates to the clients. This polling pattern replaces
the previous push on change pattern and will make it easier to do per
client throttling and per scene presence terrain update ordering.
This is to allow small adjustments of less than 0.05m in functions such as llSetPrimitiveLinkParams() to work
This is another fix for http://opensimulator.org/mantis/view.php?id=7044
Extends regression test for this case.
region. This is a temp fix for the use of draw distance to compute child
regions. Eventually must use the draw distance from the viewer for the
computation.
Fix odd "cannot cross into banned parcel" viewer error message when crossing
into non-existant region. Proper permission failure messages are now returned.
This commit eliminates all of the 'border' class and list code and replaces
it with testing if in the current region.
Impacts: can make a mega-region out of varregions of the same size; and
mega-region combinations must be rectangular (not square but rectangular)
the size of the input stream. This is required since the raw heightmap
format (.r32) does not contain any size information.
The estimation relies on terrain being square.
Modify archiver to use terrain merging when loading oars.
This makes displacement AND rotation properly work on terrain when loading oars.
Especially useful when loading legacy region oars into large varregions.
Locking attachments then launching script instances on a separate thread will not work, attachments will simply be unlocked and vulnerable to race conditions.
removed, when a script is removed, or when a script is reset. Also
added a stats command to track the number of json stores used by
a region. Will probably add some more commands later.
Changed UuidGatherer to use 'sbyte' to identify assets instead of 'AssetType'. This lets UuidGatherer handle Materials, which are defined in a different enum from 'AssetType'.
Adds displacment to all objects and terrain loaded from the oar.
As an example, if you have a 512x512 region and an old 256x256 oar, doing
load oar --displacement "<128,128,0>" oarFile.oar
will load the object (and terrain) into the middle of the 512x512 region.
If displacement is not specified, 'load oar' works like it always has.
If you have a 5
This can happen under poor network conditions if a viewer repeats the message send
If this happens, physics actors can get orphaned, which unecessarily raises physics frame times

actual crossing mechanics for seated avatars, using the supporting code from
the previous commits. Physics is not supported yet, although some few bits
for them are already in place due to the earlier code drops. With this commit,
crossing sitting avatar by "editing" the prim across the border, by using
llSetPos or keyframe motion may already be possible. Vehicles will come next.
Rename 'RegionWorldLocX' to 'WorldLocX' and same for Y and Z.
This keeps the downward compatibility and follows the scheme of 'region'
and 'world' location naming that is happening in the Util module.
These stopped working because current code calculates sit heights based on avatar physics rather than appearance data.
Also changed BasicPhysics to not divide Z param of all set sizes by 2 - there's no obvious good reason for this and basicphysics is only used in tests
- Parts of region crossing code
- New bakes handling code
- Bakes now sent from sim to sim without central storage
- Appearance handling changes
- Some changes to sitting
- A number of unrelated fixes and improvements
It turns out that the x/y rot data in mouselook is needed to implement this and to push the avatar against the ground if walking in mouselook.
Doing this in the terse send so that we preserve mouselook rotation information
Fixes http://opensimulator.org/mantis/view.php?id=3274
When not in mouselook, avatar only sends rotations around the Z plane (since that's the only way an avatar can rotate).
However, in mouselook it also sends X and Y information. But sending X and Y in terse updates causes issues with wrong camera movement in mouselook.
So strip out X and Y components for now. If this is an issue, then could strip out before sending avatar terse update, though this generates more cpu work.
Thanks to mirceakitsune for suggesting an initial fix
AGENT_CONTROL_STOP is specified to SP.HandleAgentUpdate if the user holds down the space bar on a viewer.
For a stopped avatar, this prevents fly or walk/run (though not rotate) until released.
For a walking/running avatar, this reduces movement to half speed.
For a flying avatar, this stops the avatar.
These are observed behaviours on the LL grid - there was no previous OpenSimulator implementation
This commit introduces an optional parameter to SP.AddNewMovement(), which means that it will no longer compile on .NET 3.5 or earlier versions of Mono than 2.8
Currently, this does not work for jumping, and if used whilst flying the avatar continues the fly animation even though it does not move
Unlike LL, OpenSimulator currently uses this stat to record the number of prims in the physics simulation, even when they are at rest.
Added regression test for this case.
Routines in Util to compute region world coordinates from region coordinates
as well as the conversion to and from region handles. These routines have
replaced a lot of math scattered throughout the simulator.
Should be no functional changes.
