demo_client_unaccelerated ignores stride

[Daniel van Vugt]

demo_client_unaccelerated.c: region->stride is ignored, and _assumed_ to be 4*region->width.

static void render_pattern(MirGraphicsRegion *region, uint32_t pf)
{
    uint32_t *pixel = (uint32_t*) region->vaddr;

    int i,j;
    for(i=0; i< region->width; i++)
    {
        for(j=0; j<region->height; j++)
        {
            pixel[j*region->width + i] = pf;
        }
    }
}

Also, the loops are inside-out, which makes memory access much slower.
