Added classes AIS_Animation, AIS_AnimationCamera, AIS_AnimationObjectLocatio. Draw Harness command vanimation has been modified to manage animation timeline. Command vfit has been extended with option -noupdate. Formatting of vviewparams command output has been improved. Functionality of commands vlocreset, vlocmove, vloctranslate, vlocrotate, vlocmirror, vlocscale has been merged into vlocation/vsetlocation. vlocation now can print the current local transformation of the object. v3d/ivtk test group does not call vfit anymore. Fixed misprint in test cases bugs/vis/bug24623_3 and bug25532.
