[cairo] Overlay problem for two texts

[Eric Feillant]

Thanks Mohit,

Still no success. There's a mistake in my program because if i 
substitute the var joueur1 with a static fixed text :
cairo_move_to(cr, 10, 50);
cairo_show_text(cr, "MY_TEST_TEXT");

Nothing is displayed in the image .

Something wrong i the loop but i don't know where.

I also have inserted something to trace the program:
cairo_move_to(cr, 10, 50);
system("/usr/bin/touch ./AM_I_EXECUTED?");
cairo_show_text(cr, "MY_TEST_TEXT");

The file ./AM_I_EXECUTED is created .....

No idea.
