AIS_Dimension::GetTextPosition() and AIS_Dimension::SetTextPosition() methods were added.
Added possibility to set and unset text label alignment respectively to the attach points after text position changed.
Added test cases to check text positioning with dimension parameters and with setting 3D point.
Corrected DRAW commands vmovedim, vangledim, vdistdim, vradiusdim.
Corrections of AIS_Dimension::SetTextPosition(): aspect parameters are not changed inside it.
Layout mode was removed; test cases and vdimparams, vdimension commands were corrected.
remarks: coding style, removing redundant code of LayoutMode enumeration.

+//! Such set of parameters that consists of:

+//! can be uniquely replaced with text position in 3d space. Therefore, there are methods to convert

+//! and extension size) are adjusted on presentation computing step, user-defined values in
+//! dimension aspect are not changed.
+//! But plane and flyout as dimension position parameters are changed by SetTextPosition() method
+//! according with user-defined text position.
+//! If parameters from the set are changed by user with calls of setters, it leads to disabling of
+//! fixed text position (myIsFixedTextPosition is set to FALSE).
+//! If the fixed text position is set and geometry is changed by user (SetMeasureGeometry() method
+//! is called) and the geometry doesn't satisfy computed dimension plane, the dimension is not valid.
+//!
+//! - If the set of parameters was set by user (may be without the user-defined plane or with it),
+//! it can be converted to the text position by calling the method GetTextPosition(). In this case
