[Tickit-dev] Released: Tickit 0.45

[Paul "LeoNerd" Evans]

Another week, another Tickit. 0.45 is mostly internal changes to
support the current "move RenderBuffer to C" effort:

 * Move RenderBuffer's linemask-to-character method and most of the
   Tickit::Test::MockTerm implementation into C

   The latter has been possible because of a change in libtickit, which
   now allows a new TickitTerm instance to be constructed by giving a
   struct of driver methods. This will eventually allow the MockTerm to
   be moved to the C library entirely, though will also be useful for
   writing other TickitTerm drivers for other uses (e.g. MSWin32).

 * Don't emit INSERTCH DELETECH events from MockTerm

   The mock terminal will now always emit a single SCROLLRECT event
   for a single successful ->scrollrect method call, regardless of what
   kind. I didn't announce or deprecate this one first, because I fixed
   up the only instance on CPAN that it would affect, and also because
   it's only a test-time change which simply makes a Widget test fail;
   it doesn't affect actual running code.

 * Various deprecation announcements and warnings

   As listed on
     https://github.com/ingydotnet/tickit-info/blob/master/TickitDeprecations.md

Expect for 0.46:

 * Further work on moving RenderBuffer to C

   Now the MockTerm is in XS, I next want to remove all the perlisms
   from its implementation, before moving that into the libtickit C
   library.

   Once that's done, RenderBuffer's flush_to_term method can be moved
   into XS and then the C library as well. This will then mark a major
   milestone in the C library.

 * Improvements to Widget sizing model

   We're now at the stage where every ContainerWidget uses
   ->requested_size to query a widget's size requirements. This is a
   good place to add the minimum/maximum size attributes, which will be
   four new attributes settable on the Widget base class itself, so all
   widgets will automatically support it.

 * More deprecation removals

   See the table on the page given above.
