Sync light state, bound shader, and various gl context states similarly to render matrices.
Texture handles now refcounted, as multiple viewer textures could ref the same handle (cubemaps do this)
Clean up gl extension loading a bit. Not necessary, but only look for ARB variants if not included in current core version. Removed unused extensions.
Use core shader api if supported, else use ARB. (FN signatures are identical. Just doing some pointer substitution to ARB if not core.)
Attempt at improving VBO update batching. Subdata updates better batched to gether per-frame.
There's probably other stuff I forgot that is in this changeset, too.
Todo: Fix lightstate assertion when toggling fullscreen with shaders off.
Hides lookat lines, nametags, and overhead voice indicators for hidden avs.
While this isn't necessarily according to spec, this keeps the ui from looking out of place with no avatar to show with it
View without space changes? Meh, doesn't matter so much.
camAvDist, camMax and camMin are now combined into:
-camPole: returns the saved pole of the highest degree
-updatePole: updates the saved pole to the highest degree when the related exception is changed
Poles are now cached in a map called m_Poles in the RlvHandler.
This hides name tags and names whenever possible, except from chat.. when not possible, falls back on anonyms
Changed: Radar no longer hidess based on @shownames, that's silly.. now radar hides names when @shownames
Radar will alert when @shownames restricted, but not when @shownametags restricted
Radar will not offer menu when @shownames or @shownametags restricted, and the IM and Profile buttons will disable.
Hopefully fixed broken RLVa logic in llfloaterobjectiminfo.cpp
Fix slightly broken RLVa logic code in llpanelpermissions.cpp
Changed: Range Finder now disallowed when minimap disabled, show loc restriction doesn't change it anymore.
Fix broken hiding of names when offering teleports; rlv_shownames param doesn't seem to always pass, work around those situations...
^-This causes some false positives, I suppose, if you offer teleport from friends list to someone in the region, but better safe than sorry.
Also Assorted Code Cleanup and sync with Alchemy
Debug Settings are AlchemyMouselookIFF and AlchemyMouselookIFFRange
Look to see if an avatar is in a nearby region always when checking if they're an estate owner.
Fairly certain this adds the feature in which the user may click the online notification to open a chat with the user coming online.
Translators may want to look at the xml changes of this change to see what to update
Removes old LegacyMultiAttachmentSupport patch
Moves LLAvatarName-centric functions into LLAvatarName from elsewhere.
Adds boost::signals2::connections to name polling places.
Removes more old icky static callbacks
Merge from Alchemy, credit where due~
Update notifications.xml to have a bunch of the tags from upstream to ease diffing
