i'm seeing some bizarre numbers like:
Program received signal SIGINT, Interrupt.
rect_list_add_split_fuzzy (tb=0x8092fc8, x=<value optimized out>, y=399,
w=<value optimized out>, h=<value optimized out>) at evas_tiler.c:666
666 else if ((intra.width == current.width) &&
(gdb) p intra
$18 = {left = 1, top = 0, right = -5992, bottom = -16385, width = -343,
height = 1, area = 4040884}
(gdb) p accepted_error
$21 = 1024
(gdb) p current
$22 = {left = 0, top = 405, right = 155, bottom = 477, width = 155,
height = 72, area = 11160}
(gdb) p r
$23 = {left = 498, top = 402, right = 503, bottom = 406, width = 5,
height = 4, area = 20}
look at outer... then look at _calc_intra_outer_rect_area() that's meant to
fill it in.. how on earth is it getting those large negative values?
