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.
Basically, cmake doesn't support linking static libs into a shared lib.
The correct way is to just specify source files in subdirectories
directly as source files of the shared library. This patch changes that.
Also, after this commit, when DEBUG_CURLIO is defined, every call to
libcurl is printed to llinfos (or to dc::curl when using libcwd).
This introduces some API changes, like the new LLDirIterator,
that causes changes elsewhere.
It also include Log Linden's cache changes that aren't in
viewer-development yet that increase the maximum cache size
to ~10 GB.
Since curl 7.21.2 - (October 13 2010), curl_escape (a deprecated
function that will be removed in the future) changed it's behavior
and no longer escapes the characters '-', '.', '_' and '~'.
The only reasonable solution for us is to stop using it and
use our own version that mimics the old behavior. The only
other alternative would be to rename every .xml file with
escaped characters in their name upon installation, depending
on the behavior of the installed libcurl (on standalone anyway).
However, if you add to that in the future curl_escape has to
be replaced with curl_easy_escape, which is far from easy to
call as it requires a CURL to be passed for which LL invented
a wrapper in libllmessage, but did hide that (Curl::Easy is
only defined in a .cpp file), then we're better of just using
our own function, which I named LLWeb::curlEscape.
Deferred fastalpha behaves a bit better.
Pulled over patch for https://jira.secondlife.com/browse/STORM-336 and https://jira.secondlife.com/browse/STORM-1011 from linden repo
Sky rendered using new LL method. Assuming this fixes issues on AMD cards(works on cat 11.2)
Added a few things missed related to spatial-parition updating.
Added 'SkipReflectOcclusionUpdates' setting that prevents occlusion updates for reflection pass. Less taxing on CPU.
