Icon-O-Matic: Fix crashes while auto-scrolling

This fixes crashes that happen when scrolling list views in Icon-O-Matic
triggered by the BListView auto-scroll feature reintroduced in hrev57439.

Take out the auto-scrolling code from Icon-O-Matic, call BListView's
MouseMoved() instead since BListView's can scroll now. The BListView auto-
scroll feature has been updated to work with draggable multi-select.

ScrollTo(index) method has been moved from Icon-O-matic to BListView and
is used to scroll to an index instead of a selection since the selection
doesn't change while you are dragging.

Override BListItem's DrawItem() method to prevent it from drawing. I've
hijacked DrawItem()'s complete param to mean even or odd instead.

Everybody draws the same background PathListView.cpp and StyleListView.cpp
now push the frame over and draw text using SimpleListView parent class
DrawItem() instead of repeating the drawing code.

InitiateDrag got moved from the abstract DragSortableListView class to the
SimpleListView implementation class.

The following color constants have been added:
rgb_color kDropIndicatorColor = make_color(255, 65, 54, 255);
rgb_color kDragFrameColor = make_color(17, 17, 17, 255);

First one is the red drop target indicator line. It has been changed to
clrs.cc red which is the same as B_FAILURE_COLOR, but I didn't want to use
that InterfaceDef constant as it doesn't indicate failure in this case,
it's just a slightly different red.

Second one is the drag selection outline, it has been changed from pure
black to clrs.cc black which is a shade lighter than pure black.

Fixes #18707

Icon-O-Matic: Minor changes and style fixes to list views

Not 100% style changes but the functional changes are very minor.
This is to create a clean base on which to make my other changes.

Remove commented out code. Remove LIB_LAYOUT.

Replace calls to _SetDropAnticipationRect with assignment to fDropRect,
make all methods protected. Rename _SetDropAnticipationRect to
InvalidateDropRect and remove _'s from methods.

Some extra NULL checks are included in ShapeListView and it has been
de-indented.

omit .0 where it doesn't matter.
rename r to rect
tab style on classes
use SetHighUIColor/SetLowUIColor where appropriate

Also:
* make transformers draggable
* clean up archiving code

Made it easier for derived classes to handle the drop message.

* merged Icon-O-Matic from Ingos layout branch into trunk (r18134:18685)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18686 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Transformers have Name() now
* added TransformerFactory to instantiate the various types via the GUI
* added Transformer menu to main window
* added TransformerListView that shows the Transformers applied to the
selected Shape
* implemented more powerful listener interface for Shape, used by
TransformerListView


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18027 a95241bf-73f2-0310-859d-f6bbb57e9c96

* work in progress on GUI classes
- added IconView which just uses an IconRenderer to display a preview
of the icon at a certain size
- PathListView and ShapeListView (very much work in progress)
* actually had the gamma correction applied in the wrong direction...
now the anti-aliasing looks as smooth as planned
* added SetName() and Name() to Shape and VectorPath... will be in a
common base class later on

the first steps towards Icon-O-Matic
* added a framework with many classes that I think will be useful
* currently, the StateView and Manipulator interface are used to
allow editing a single VectorPath object, nothing more... the
CommandStack framework is also used to support Undo/Redo
