Can't behave well if renderers add their own arbitrary margins
and we have a rows/cols based sub

strdup() is as (un)likely to fail as asprintf().

Also use size_t for the size.

In the previous implementation was so unsafe that the ARC
compiler was not able work properly and printed a warning.

While there was no real problem here, switch to blocks to
silence the compiler and see potential errors earlier.

removes temporary text_style_Reset() and finishes
migrating decoders.

We might want to deprecate text_style_New().

use or don't use filter. -1 has no better
meaning than 0 and 0 is for new text-style

Renderer should have final decision of the styles to apply.
Rendered forced styles are applied over text-segments
ones, then renderer defaults (text-style's ones).

Also adds proportional font size.
Fixes all style inheritance and font sizing hacks in region
sys.

Final fixed font size is only computed at update time, if
not set to fixed size by decoder.

because you can't tell if members are
have set value or are unset.

avoids reordering and display delay

caption data rate is 2 bytes per frame at 30 fps

CFBridgingRelease was used in the wrong place.
All view objects should only be retained by the window (and in this
situation by the grid view dicts as well), thus they is no need to
additionally retain them for the p_sys_intf pointer.

Fixes a crash when quitting the interface during media playback.

Also deinitalizes both objects. This should fix the refcount
crash on exit.

VLCIntf now points to a static getter for the interface thread
pointer.

This fixes several problems: During initialization of
VLCMain, [VLCMain sharedInstance] is not ready yet when all other
objects are initialized inside VLCMains constructor. Due to the
way ARC works, the same applies to dealloc (the main shared instance
is nil already). But in both situations, we need VLCIntf for
callback (un)registration and potential logging.

The mac interface relies on static data in any case and does not
support multiple instantiations.

Only self should be used as callback parameters. Otherwise,
depending on the destruction order the original object might be
deinitialized already.

The window controller ensures that all top-level objects of the
mainwindow xib are properly released.

This removes the last occurence of VLCMain in xib files, thus
awakeFromNib will not be called for this object anymore. The code
