Experimental fork with sample program that crashes after some time.

ajstarks#22

There are two cases when the program crashes:

1. The screen freezes and the process goes into D state.
2. Random shapes appear on the screen, the process doesn't freeze but slows down by a lot.

Build and run

Note that you will need at least 64 Mbytes of GPU RAM:. You will also need the DejaVu fonts, and the jpeg and freetype libraries. The indent tool is also useful for code formatting. Install them via:

pi@raspberrypi ~ $ sudo apt-get install libjpeg8-dev indent libfreetype6-dev ttf-dejavu-core

Next, build the library, program and test it:

git clone git://github.com/pawelduda/openvg
cd openvg
make
cd client
make digital-signage
./digital-signage

To install the shapes library as a system-wide shared library

pi@raspberrypi ~/openvg $ make library
pi@raspberrypi ~/openvg $ sudo make install

The openvg shapes library can now be used in C code by including shapes.h and fontinfo.h and linking with libshapes.so:

#include <shapes.h>
#include <fontinfo.h>

pi@raspberrypi ~ $ gcc -lshapes anysource.c
