Instead of setting each pixel in the framebuffer, use memcpy() to clear screen faster. As this method should be fast enough, remove the fast path using memset(). The speed of clear_screen() on brya (x_resolution = 1920, bytes_per_line = 7680): - Using memset(): 15ms - Setting each pixel: 25ms - Using memcpy(): 14ms Also remove set_pixel_raw() since it's now used in only one place.
