EXT-8673: FIXED: UDP texture loading is slower in 2.x viewers than 1.23.5

Improved the following:
1, make sure the texture callback queue is properly handled and cleaned in time;
2, estimate the LLVOTree pixel area more accurately;
3, eliminate the possibility of back and forth stopping/restarting a texture fetching
