Axel Dörfler a4de7fa0fa * Do not trust the client! ServerFont::GetEscapements() now takes a
parameter for the length of the arrays, so that even if the char/byte
  counts do not match, no memory is overwritten anymore.
  This fixes bug #1862; .canna obviously contains invalid UTF-8 
  characters, or there is a bug in StyledEdit (or deeper) and it doesn't 
  call BFont::GetEscapements() correctly.
* Fixed some cases of unchecked allocations in the font handling methods
  of ServerApp, added TODOs to all other ones.
* Improved error code when creating a window fails.

Stephan Aßmus aadc09c665 * fix the mixup of charCount (glyphs) versus bytes. The new font cache
implementation takes the byte count, even though it looks like this is
  less efficient when the glyph count is already known (I tested to
  optimize it away but it was not faster)

Stephan Aßmus 2222864eed * 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

Stephan Aßmus 5fdc05c105 * make sure that the 80 chars per line limit is not exceeded

Stephan Aßmus 10f6ed940b * 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.

Axel Dörfler 16ed1e1d15 * Removed headers/private/servers/app - everything is in src/servers/app now.
* Removed DisplaySupport.h, wasn't needed anymore.
* Removed private color set functions from InterfaceDefs.cpp - we might want
  something similar, but definitely not like that.
* Minor cleanup, added some missing licenses.
