58e6f33e35 videoscale: fix 4tap for RGB15 and RGB16 
Fix component ordering, it's wrong in both the scanline and merge
function so it cancels eachother out and isn't really a except for
loss of precision of the green component.
Fix calculation of the filter weight

b3e5d55040 videoscale: remove redundant MAX 
The checks above make it inpossible for the value to be smaller than
what we check against with the MAX call.

5a58f8b9ec videoscale: Fix compiler errors caused by not including config.h 
_stdint.h requires config.h to be included to properly
use the correct code to get uint8_t and friends.

7892e1e22f videoscale: fix 4-tap scaling for 64-bpp formats 
Fix invalid memory access caused by broken pointer arithmetic.

If we have a uint16_t *tmpbuf and add n * dest->stride to it, we
skip twice as much as we intended to because dest->stride is in
bytes and not in pixels. This made us write beyond the end of
our allocated temp buffer, and made the unit test crash.

too much.
