Icon-O-Matic: Add perspective transformations

As part of adding perspective transformations, agg_trans_perspective.h
was patched to fix a multiple definitions error. This change has been
submitted for review to the "upstream" repositories at [1], [2],
and [3].

Also includes various other improvements such as VertexSource being
split into its own file, code style improvements, and documentation
improvements.

More catalog-related cleanup.

* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h

The renamed macros require adjustments to all external applications
using catalogs.

* Removed PI, and PI2 from math.h.
* Replaced all occurences with the standard macros M_PI, and M_PI_2.
* Some coding style cleanup on the touched files, no other changes besides
adding a missing check for a failed memory allocation.

* added a little bit of tracing to object destruction, since there
seems to be a problem when quitting the app
* added Undo/Redo commands for numerous operations
- (un)assigning VectorPaths to Shapes
- adding new VectorPaths
- removing VectorPaths
- adding Shapes
- transforming Shapes
- adding Styles
- changing Style color
* there was a mix up in classes inheriting from SimpleListView,
RemoveItemList() gives a list of item pointers, not indices
* GradientControl sent the focus notification to the window instead
of the set BHandler target
* StyleView takes care of transfering the current Style color or
the focused gradient stop color to the CurrentColor object, so
the current color of the SwatchGroup is synced
* small improvement to layout of SwatchGroup
* SwatchGroup no longer knows anything about a Style
* fixed syncing the global Selection to the listview selection
at least for ShapeListView
* implemented cloning Shapes
- added Transformer::Clone(VectorSource& source) to all Transformers
- ShapeListView uses this when dropping shapes with shift pressed
* updated NOTES
* added Transformable::matrix_size, so that "6" isn't hardcoded
everywhere (though it still is at most places)
* added listener interface to TransformBox, this is used by
the new TransformObjectsCommand, as long as the TransformBox still
exists, the command modifies the TransformBox transformation instead
of messing with the objects itself
* fixed hotspot size in TransformBox by using the zoom level of
the CanvasView
* TransformBox rotates/scales correctly around the visible pivot
* fixed TransformCommand toggling to transformation (the diff was bogus)
* Gradient doesn't trigger unnecessary notifications in SetColor()
* CanvasView doesn't eat keyboard events when the GradientControl or
one of the ListViews has focus (is a hack currently...)
* fixed bug in PropertyListView when it calls the PropertyChanged()
hook: because of the notification mechanism, the Properties might
be toast after the hook returns
* moved all GetProperty() implementations from headers into .cpp files

* added a framework for affine transformations and manipulating them
- Transformable: the base class with a nice interface to agg::trans_affine
- ChannelTransform: inheriting from Transformable, keeping the affine
parameters separate
- TransformBox: inheriting from ChannelTransform and Manipulator
- TransformShapesBox: transfering the TransformBox transformation onto
multiple selected Shape objects
* Shape inherits from Transformable
* solved an important TODO in IconRenderer: a Gradient is now transformed
along with a Shape
TODO: Undo/Redo for manipulating the transformation
