When using AIS_AnimationObject, linear interpolation is performed from one gp_Trsf transformation to another.
But when an object rotates around a specific axis, the object moves not along a linear trajectory,
but along a circle. Therefore, a separate class AIS_AnimationAxisRotation was created that
allows to animate rotation around a specific axis.
Test case tests/v3d/bugs/bug32570 was added.
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.
