* src/misc/modules.c: only set b_force when we have b_strict.
* src/input/demux.c: add m4v and h264 extensions.

- use nearest integer value from integer division (i.e. round() ) in volume and time calculation, looks more accurate that way.

- Optimized clipping, removed the extra child window which prevented some buggy Intel DirectX drivers to render (can't handle too many sub-windows ?). Resizing looks smoother on IE, needs a lot of compatiblity checks on other apps such as VB, Delphi, etc...
- Fixed initial volume setting

* major speed and memory improvements to the image handling (the panel launches noticebly faster now) and controls 
* coding style fixes

- just FYI: The VLCFSVolumeSlider and VLCFSTimeSlider classes will be merged later on to add as little code duplication as possible.

Re-enable mad decoder on OSX. It was disabled because it was a CPU hog, but the issue seems to no longer be a problem

Make use of psz_trackid in audioscrobbler.c
Reading of this data is only implemented in vorbis.c
taglib.cpp and id3tag.c need to be updated

For the records: please don't re-invent the wheel, also if there are only 2 places which already do the exact same thing and you're going to add the 3rd place!!

src/input/item.c: if we don't have an item name and item is a file, then only use the filename (and not the full path) as the item's name
others: if we only have a path and no interesting name, let the core decide what name to use

use config chain for the --sub-filter option.
Example:
  --sub-filter "marq{marquee=pouet}:marq{marquee=\$N,y=50,x=50}"
Sub filters other than marq still need to be changed
rc interface marq callbacks need to be fixed too
