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.
Solves Issue 1131: Inspect Window while open prevents camming
Possibly fixes Issue 928: Have to Click a second time to Inspect an object, I couldn't reproduce, but maybe you still can?
Fixes a bug in the name cache connection setting of llfloaterinspect.cpp from upstream.
When the login panel used to die, it now hides instead, we only truly kill it upon successful login.
Much of the opening and setting behaviors have been cleaned up to ensure fields are autofilled by the viewer without any user action once
Everything else like changing saved logins will still work the same.
All edit keys now work, but Ctrl-A still doesn't work right, it must be grabbed by something else...
Adds LLFocusMgr::keyboardFocusHasAccelerators()
Adds virtual bool LLView::hasAccelerators() which returns false by default, overrides returning true placed in LLPreviewScript and LLPreviewNotecard
Shortcut keys added to notecard and script menu xmls
I'm thinking Qarl's Align tool handling may be receiving the Ctrl-A, we do seem to handle it differently than Exodus and Firestorm something modern could have broken the old way..
Come to think of it, those two features(Align and Select all prims) have a longstanding shortcut conflict in shortcuts... that's pretty nasty
-Idle tick is now responsible for dispatching all pending sound sources, as such improves priority sorting.
-Added ui sound precache mechanisms (to fetch sounds without associated soundsources)
-Audio engine no logner available pre-login or upon disconnect, for simplicity.
-General cleanup to the audio engine/impl.
-Fixed some gAudiop calls that were lacking prerequisite null checks.
-Added 'isUpstreamOK' procuedure to LLAssetStorage to allow avoidance of making requests when there is no upstream host connection.
