modules/video_filter/osd_text.c: A video filter that uses freetpye2 to 

render text on the video
include/osd.h: some constants useful when interfacing with the osd module
configure.ac.in: check for freetype2, enabled the osdtext module by default
Makefile.am: added osd.h, please check that this is correct
lirc.c: modified to provide feedback when buttons are pressed.

Look at the Feedback() function in lirc.c to see how this module can be used
