Scaling fails with linear (p-)curves
Description
Post from the Forum http://www.opencascade.org/org/forum/thread_20945/.
RLN:
====================================
OCC 6.5.0.
If a face's edge lies on linear curve and (?) pcurve scaling produces wrong model.
DRAWEXE reproducer:
- pload MODELING
- pcylinder p 10 50
- explode p f
- tscale p_1 0 0 0 0.001 #p_1 is a cylindrical face
- tscale p_2 0 0 0 0.001 #p_2 is top planar face
#p_1 is wrong, p_2 is fine
- cylinder c 50
- mkface f c 0 5 0 10
- tscale f 0 0 0 0.001
# f is wrong
My assumption is that tscaling sets wrong SameRange/SameParameter flags - it
keeps them true while ranges have changed and no longer match each other.

As confirmed by RLN, this is false report.
However, test case deserves to be created in OCCT database, also in the view of
expected integration of RLN fixes, one of which is likely a reason of such bug.

I suggest we add a test case (just add checkshape to Roman's commands) and close the issue
