- check for invalid tiles / buckets, which occurs at the poles
- use .sibling() method to offset
- no longer need to store view lat/lon in the manager.
Adapt to corresponding SG change to make SGMaterialLib be ref-counted,
and have the 'reload-materials' command notify the tile-manager of this,
so it can update the options struct it passes to new tiles.
When tiles are being loaded, re-evaluate the materials cache once
per update cycle. (This is probably too often, but no worse than the
previous approach).
Using a new TerraSync API, make the tile manager wait on actively
syncing tiles before sending them to the SceneryPager. This resolves numerous
issues with missing tiles, including at startup.
Make position finalisation happen in the same phase as scenery load, i.e as a task during the main loop, instead of during the init loop. This is compatible with the existing reset logic. Unfortunately more work is needed; the environment code doesn't update the local station quickly enough on reset. (Fixing that is next!)
SceneryPager singleton must not be removed while FGScenery is still alive,
so hold a reference to it in FGScenery, saving the pager from being
deleted first.
Aircraft could fall through the ground on scenery reload. Properly reset
the "sceneryloaded" flag to pause FDM processing while scenery is being
reloaded. Also stop processing some instruments while scenery is reloaded.
This way of scenery paging is really application code.
Now that the simgear stg loader is seperated from the paging
code, this appication specific paging can reside here.
May be at some time also use the spt stuff here.
Instead of PagedLOD nodes use ProxyNodes for models in
scenery tiles. This should lower the amount of PagedLOD nodes
in the active scene. Since the models are part of the to level
tiles they are then paged out once the tile is paged out.
When a model is not found in the custom scenery directories, load data
from base-package (instead of trying to access file "").
Also allow paged models to be loaded from custom scenery folders.
Priority scheme for tile loading/removing
Cleaner tile manager interface for AI/groundcache/...
Reduce start-up delay. Drop splash screen when inner scenery is available.
Be nice to osg loader: slow-down main loop while initial scenery is still loading.
