[Devel] 2.1.5 ready and other changes

[Turner David]

Hello,

 

  I've released FreeType 2.1.5 to the FTP server and SourceForge yesterday

  night. Though the web site hasn't been updated, you can start downloading

  it right now. Note that this doesn't include some recent fixes (like the PFR

  ones), since it's only the second release candidate without the warnings

 

  Additionally, I've commited some rather important internal changes to the

  font engine on the HEAD branch. These introduce the notion of "services"

  (really "interfaces", i.e. structures containing function pointers), which

  generalizes the export of dynamic interfaces by modules.

 

  One simplification is that the list of all "services" is now in a new

  directory called "internal/services". For now, only a small part of the

  engine has been converted to this new scheme, but the rest will

  follow.

 

  Hopefully, this will allow us to simplify many internal things within the

  font engine, like the way glyphs are loaded, hinted, allowing reliable

  support for the unpatented hinter, and more..

 

  Another idea is to make the code clearer for maintainers, hackers.

  This will however break the module ABI significantly, so authors of

  third-party font drivers will need to update their sources to the new

  scheme. This also might be a reason to call the next release 2.2.0,

  but we'll see..

 

  More details on this when the migration will be over.

 

Regards,

 

PS: Don't forget to use the "-d" flags when doing a CVS update to

      retrieve the current sources. You won't get the new directory

      otherwise.
