Released Esenthel for Windows, Mac and Linux:
-motion blur now takes into account skeleton bone angular velocities
-increased precision of 'GetDelta', 'GetVel' functions
-added one more variation of 'GetDelta', 'GetVel' functions accepting position of 2 steps in the past, allowing for more precise calculations for circular movement
-small improvements to Quaternions
-added new class 'QuaternionD' with double precision
-optimized setting shader matrixes and velocities for skeleton-animated meshes
-reduced memory usage for Animated Skeletons
-added new method 'AnimatedSkeletonBone.pointVelL'

Fixes:
-fixed a bug when multiplying a matrix by itself and storing result in self too
-fixed 'GetDelta', 'GetVel' returning inaccurate values if matrix was rotated on more than 1 axis
