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).
- allow multiple model files in the -set.xml specification
- allow each model to be tagged with a usage string
- put models tagged 'interior' into a LOD group.
This is experimental, the LOD ranges will be made configurable soon.
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.
This adds the framework for platform cursor implementations; Windows and X11 to be done.
It also extend the mouse-input code to generate hover events suitable for driving tooltips.
Note there should be no visible functionality change from this commit, since everything
is inactive until fgdata changes are made.
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.
