* commit 'joel/gui':
Correct a liblumi to liblumiera
Added track tree support and added widgets to headers
Corrected a selection rendering bug in TimelineBody
Added linkage to the proc layer
Made GtkLumiera and WindowManager boost::noncopyable
Added the backend as a lib, and included the interface header
Showed some love to viewer panel
Changed the "delete" variable name to "del" to satisfy the C++ compiler
Renamed HeaderContainer to TimelineHeaderContainer
Conflicts:
src/gui/Makefile.am
calling 'luidgen' with a list of filenames replaces the word LUIDGEN in
each of this files with a octal escaped string consisting a unique
identifier
add luid formatter help macros to luid.h
let compilation of files which contain the word 'LUIDGEN' fail with a
hopefully self-explaining error message
This *must* be replaced by a real luid with a upcoming luidgen tool ASAP,
luids starting with zeros are invalid. For the time until this luidgen tool
is not ready we just leave it this way. Later it will be changed to give a
compile error.
* lumiera_interface are now static structures, never wrritten
* introduced a lumiera_interfacenode which manages the dynamic data
of interfaces. The interfaceregistry now holds this nodes.
When interfaces cross depend on each other nested acquiring from
their acquire handlers would introduce cyclic references which cant
be cleaned easily. By flagging such nested acquisitions as weak the
respective handler functions can account for this.
Example: maintain 2 ref counters one for strong and one for weak
acquisitions. At release time all acquired nested handles get closed when
the strong counter drops to zero, which causes that cross reference
releases will eventually drop the weak count to zero too. Then all
resources can be freed and the interface is properly shut down.
Provides structures used for managing interfaces, macros for declaring
and defining interfaces. Convinience macros to bundle buildin and plugin
interfaces.
Recursive mutex can be locked multiple times by a single thread they
are initialitzed by lumiera_recmutex_init() and used by LUMIERA_RECMUTEX_*
macros.
Chained mutex use the mutexacquirer from the outer scope now. Maybe its
later needed to pass acquirers explicit, we will see.
