Icon-O-Matic: Remove "using namespace" from header

Putting a "using namespace" statement (_USING_ICON_NAMESPACE in this
case) in a header file causes all source files that include that
header to use that namespace, regardless of whether they actually
wanted to.

libicon: Notify Shape on transformer addition/removal

hrev57144 accidentally made Shape be notified only if the library was
compiled for Icon-O-Matic.
Also includes some miscellanious improvements.

Fixes #18510

Icon-O-Matic: Generalize some classes

* Turns PathContainer, ShapeContainer, StyleContainer into Container.
* Makes Shape use Container for storing Tansformers instead of
reinventing the wheel yet again.
* Moves common logic from AddPathsCommand, AddStylesCommand,
AddShapesCommand, and AddTransformersCommand to AddCommand.
* Factors out common logic from two more commands similar to above.
This adds the MoveCommand and RemoveCommand classes.
* Cleans up some code style.

Enable just enough of the message based format used in Icon-O-Matic to allow
BIconUtils to understand and render it. This makes it possible to use the
HVIFTranslator to also read Icon-O-Matic files out of the box. Will cleanup
now duplicated files next.

* make sure that the ApproximationScale() implementation of any Transformer
not negative
* PathSource can now remember a global scale, and the IconRenderer sets
it, since this value is used in the curve converter for on the fly
generation of vertices, this change does not affect anything and doesn't
create the need to "update" the conversion pipeline to render an icon at
different sizes (like Icon-O-Matic does)

-> this change fixes edgy curves on icons rendered bigger than 64x64 as
reported by Axel some time ago
