TODO
----
- YUV to RGB conversion
- mmap support
- fix bug: deadlock when trying to save an image after having stopped the capture process. Thus doing Camera>Stop Capturing and then File>Save
- there should be only one way to save to a file (ppm_save, png_save, etc). currentely there are three different paths that lead to them.
- adjust autobright
- GUI: make window resizable
- debug: add cmd option to print useful info while running
- autotools to configure and build application
- add keyboard accelerator to most common actions
- fix bug:
Gtk-CRITICAL **: file gtkwidget.c: line 3310 (gtk_widget_set_sensitive): assertion `widget != NULL' failed.
- modify jpeg module to avoid stopping the application in case of format error (see call to ERREXIT in jpeg.c).
- add option telling not to load the config file
