ImGuizmo::Manipulate dont returns true on bounds manipulation

Hello,

Is there any reason for ImGuizmo::Manipulate not returning true on bounds manipulation. I would find it useful because I only modify object matrix when Manipulate returns true.

no good reason. I'll be glad to review a PR for that :)

I have tried monitoring scale on HandleAndDrawLocalBounds (https://github.com/CedricGuillemet/ImGuizmo/blob/master/ImGuizmo.cpp#L1894) by checking the length of the three vertical vectors on that matrix. I expected that lenght==1 would mean bounds are not changed, but sometimes this values are not 1 even if bounds are not modified (just doing mouse click on a bounds point) If mouse if clicked again on the same point values are then 1.
