The code goes like this:
Dialog_Partition_Copy::Get_New_Partition()
call Dialog_Base_Partition::Get_New_Partition()
Update this->selected_partition with results from running
the dialog.
return this->selected_partition by value.
Save value back to this->selected_partition.
Update this->selected_partition some more.
return this->selected_partition by value.
So there is an unnecessary copy of the partition object returned from
the base class Get_New_Partition() function back to the same variable in
the derived copy class Get_New_Partition() function.
Need to keep the base class Get_New_Partition() function as derived
class Dialog_Partition_Resize_Move uses that implementation as it
doesn't override it, and it's part of the interface.
Avoid this unnecessary copy by moving base class Get_New_Partition()
code into a new private function, called prepare_new_partition(), which
doesn't return anything. Then have Get_New_Partition() in both classes
just return the required partition object. Like this:
Dialog_Base_Partition::Get_New_Partition()
call prepare_new_partition()
return this->selected_partition by value.
Dialog_Partition_Copy::Get_New_Partition()
call Dialog_Base_Partition::prepare_new_partition()
Update this->selected_partition some more.
return this->selected_partition by value.
Bug 750168 - Reduce the amount of copying of partition objects
This commit from 2010-05-20 removed use of cylinder size increase in the
minimum, and cylinder size decrease in the maximum file system sizes
from the resize/move dialog.

Add partition alignment option to align to MiB (#617409)
This cylinder size limit adjustments were being performed using the
Dialog_Base_Partition::BUF member variable. Now in the
Dialog_Partition_Resize_Move class it is never accessed, and only
unnecessarily set. Move BUF from the common base class into the
Dialog_Partition_Copy class where it is still used.
Bug 749867 - Some limits are adjusted by arcane cylinder size amount
when copying and resizing in a single operation
This is part of parent bug:

Include guards need to be unique within GParted code and all included
library header files.
http://en.wikipedia.org/wiki/Include_guard#Difficulties
Use this model for all include guards:
#ifndef GPARTED_FILE_NAME_H
#define GPARTED_FILE_NAME_H
...
#endif /* GPARTED_FILE_NAME_H */
Closes Bug #539297 - Make include guards unique
Steps to reproduce:
1) Open any of these dialogs: Create New Partition, Resize/Move or
Paste;
2) Update any of the following numeric entry fields to a different value
using the keyboard: Free space preceding, New size or Free space
following;
3) Press [Esc] key;
Gparted crashes.
What is happening is that the [Esc] key is leading to the dialog being
closed and calling the ~Dialog_Base_Partition() destructor. However
after this the GTK widget is calling the on_spinbutton_value_change()
registered callbacks for the change to the other two values, on the now
just deleted object.
Fix by disconnecting the change notification callbacks in the
destructor.
Closes bug #682658 - GParted crash by pressing Esc in dialogs with
number entry
Some classes contained private attributes which were used only by a single
member function. Such items were moved to the corresponding function implementations
to stress their limited usage scope.
A few unused variables were also deleted.

Make align to MiB the default setting instead of align to cylinder.
Migrate logic for alignment to cylinder into its own method
snap_to_cylinder, and place common logic in snap_to_alignment.
Add alignment checks for situations where space is needed for Master
Boot Record or Extended Boot Record.
Adjust ranges on spin buttons according to required boot record space.
Copy fix for off by one sector (#596552) from
Dialog_Partition_New::Get_New_Partition to
Dialog_Base_Partition::Get_New_Partition
Enhance resize / move logic for checking locations of nearby logical
partitions to not depend on the partition ordering.
Note: This commit does not include limiting graphic movement according
to required boot record space.
Also add signal handler to alignment menu to update file system
minimum size.
This enhancement is to prepare for adding a third alignment
option to align to MiB.

Add my own copyright entries for files in which I changed source
code. Files in which I only made spelling changes do not have my
copyright entry added.
* include/Device.h,
include/Dialog_Base_Partition.h,
src/Dialog_Base_Partition.cc: replaced 'long' with 'Sector' to
prefent overflows with really large devices.
* include/Dialog_Base_Partition.h,
src/Dialog_Base_Partition.cc,
src/Dialog_Partition_Copy.cc,
src/Dialog_Partition_Resize_Move.cc: Fixed bug in copy functionality (due to unset ORIG_START startsector wasn't set correctly). Also have ORIG*
initialized in ctor of dialogbase to prevent such errors from ever happening again (this one only showed up with gcc-3.3.5) .
* added MIN and MAX to filesystemstruct to set min. and max sizes of a filesystem. So instead of checking per filesystem
i now simply check the fs.MIN or fs.MAX. this results in less and cleaner code. Also this will come in handy when adding
support for new filesystems. (This also fixed several minor bugs with filesystemsizes and gained some improvement in resizer
performance)
* Rewrote a large part of gparteds internal code. Filesystemssupport is now much more separated from the rest of gparted and
adding support for other filesystems should be a piece of cake now (hope that's true :P)
It still needs a lot of love, but the foundations are laid =)
