[Opensim-users] Hypergrid 1.5 jumps over 6K reproducible

[Diva Canto]

Clarification:

The 4096-limit bug has nothing to do with the Hypergrid. You bump into 
this same limitation by having two regions on the same grid that are 
separated by more than 4096 map cells in either axis. So, for testing if 
viewers have fixed this or not, simply have two regions, one at 
1000,1000 and the other at, say 7000,7000. If you can TP between the 2, 
and things look normal upon arrival, then the bug is fixed in that 
viewer. Let me know when that happens.

The reason why this bug got highlighted in HG TPs is that in the HG 
people don't have any control over the absolute coordinates where other 
grids place the regions; specifically, OSGrid is placed around 10,000 
whereas standalones, by default, are placed around 1000.(Whereas within 
one grid operators usually place the regions very close, and those long 
jumps simply don't exist.) In order to avoid a series of issue reports 
of the kind "TPs not working in HG -- nothing rezzes upon arrival", I 
added that check to prevent those long jumps in HG TPs.

As soon as someone confirms that viewers have fixed this, I will remove 
the check in HG TPs.
