Implementation of BFont::Blocks

BFont::Blocks is now implemented in ServerFont, via a call through the
app_server. It uses fontconfig to iterate through a charset of a font
and stores the defined blocks in a bitmap.

A new API was added, BFont::IncludesBlock, that will allow for arbitrary
testing of a given Unicode block. Since nothing is cached, searching
through an entire charset for a series of Unicode blocks can be quite
slow. In a given block there may be only 1 or 2 characters actually
defined so every character within a block needs to be checked until one
is found, which in a degenerate case will mean the entire block is
checked.

# 95fdee0b 21-Jan-2015 Axel Dörfler <axeld@pinc-software.de>

BStringView: added truncation support.

* Added new truncation mode B_NO_TRUNCATION.
* The Truncation()/SetTruncation() methods itself are Dano-compatible,
however, there was no B_NO_TRUNCATION.

Fix some pedantic style issues in Font.h


# 89208c77 27-Aug-2009 Stephan Aßmus <superstippi@gmx.de>

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.

# 5b30a26b 24-May-2008 Stephan Aßmus <superstippi@gmx.de>

Added additional font face flags for "condensed", "light" and "heavy".
Our font has some extra styles and these could be picked up as the
"regular" face by accident, as witnessed by Firefox. Tracked down by
Michael Lotz. Firefox uses the correct font now for it's interface.

# f6e4cbb9 15-Oct-2007 Axel Dörfler <axeld@pinc-software.de>

* Rewrote BeBuild.h which had "a few" consequences (got rid of all those class
definitions).
* Minor cleanup here and there.

# 2222864e 02-Aug-2007 Stephan Aßmus <superstippi@gmx.de>

* complete overhaul of the font/glyph caching
* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
read/write locking to the list of cache entries (fonts) as well as
read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
glyphs along the baseline.
It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the
actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
is the same, which of course it isn't, hence the two separate functions...
AsGlyphs just gets the bounding box of each glyph in a string, not treating
the string as an actual word
AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning

# 10f6ed94 17-Dec-2006 Stephan Aßmus <superstippi@gmx.de>

* implemented "false bold" for text rendering. It is a new property
of BFont. You can BFont::SetFalseBoldWidth(float) a width on a
BFont object, and it will cause the glyph shapes to be run through
an AGG "contour converter" so that they become thicker or thinner.
IIRC, this is commonly referred to as "false bold". The "width" value
is the distance in pixels that the new glyph outline will be offset
from the original outline.

It would be nice if someone could look at my change to View.h with
regards to the B_FONT_ALL flag.

BFont::_GetExtraFlags() no longer returns a status value, but fills in default
values in case the server communication failed.

# b2cc3454 07-Nov-2005 Axel Dörfler <axeld@pinc-software.de>

More font work:
* Simplified server communication a bit: instead of separate queries for font
direction, "is fixed", ... there is now a private extra flags field that is
filled on demand.
* The server command names now describe what the command does, and are not simply
named after the BFont method (AS_SET_FAMILY_AND_STYLE vs. AS_GET_FAMILY_AND_STYLE_IDS).
* Replaced B_SET_SYSFONT_{PLAIN|BOLD|FIXED} with a single B_GET_SYSTEM_FONTS.
* Rewrote Font.h and added our license.

than casting away the const.
