Ancestors: Graphics-mt.441, Graphics-ct.439, Graphics-ct.430, Graphics-ct.425, Graphics-ct.418

Merge Graphics-mt.441, Graphics-ct.439, Graphics-ct.430, Graphics-ct.425, Graphics-ct.418

Graphics-mt.441:
	Some clean up around DisplayTransform. Thanks to Stephan Lutz (stlu)!

Graphics-ct.439:
	Fixes transparency handling in Color >> #negated. Negating a color should not remove its alpha channel.

Graphics-ct.430:
	Miscellaneous minor refactoring

- Use #ifError: and correct deprecated [:argWithoutBar] block syntax (see Compiler-ct.417)
- Fix a documetation typo
- Simplify some conditions

Graphics-ct.425:
	[very minor] Use already defined magic number instead of hard-coded duplication

Graphics-ct.418:
	Add Color>>#veryMuchDarker

We also have #veryMuchLighter, so balance this out :)

+ FormSetFonts are designed to capture individual images as character forms for imbedding in normal text.  While most often used to insert an isolated glyph in some text, the code is actually designed to support an entire user-defined font.  The TextAttribute subclass TextFontReference is specifically designed for such in-line insertion of exceptional fonts in normal text.!
