The fix in fllowing:
LLTextureFetch has object LLTextureInfo which is has Recorder object.
The recorder object activate (Recorder::handleStart()) self AccumulatorBufferGroup
(Recorder::mBuffers into the current (LLTrace::get_thread_recorder()) ThreadRecorder object
which created (as I understand) one per thread, and time to time send accumulated data to the master ThreadRecorder.
The problem is that LLTextureFetch also can uses from the main thread.
I decide add parameter to CTOR LLTextureInfo(bool postponeStartRecoreder) -
if it false the recorder start immediatly in LLTextureInfo CTOR body, if true we need to start it manually.
Also I add another one LLTextureInfo in LLTextureFetch::mTextureInfoMainThread which is intended
for accumulate data from the main thread.
The postponed Recorder started/stoped from LLTextureFetch::startThread()/endThread().
continued conversion to units system
made units perform type promotion correctly and preserve type in arithmetic
e.g. can now do LLVector3 in units
added typedefs for remaining common unit types, including implicits
