AIS_Shape and AIS_ColoredShape now computes Shaded presentation with UV coordinates if texture mapping is enabled in Drawer. OpenGl_Context::SetTextureMatrix() - fixed inconsistent handling of texture cooridnates translation vector. vtexture command has been extended to handle new arguments: * -trsfTrans, -trsfScale, -trsfAngle defining transformation matrix * -setFilter, -setAnisoFilter to setup texture filtering
