Wan-Teh Chang 1e2e3a3599 Avoid integer overflow if src_height == +/-32768 
The ScalePlaneBox(), ScalePlaneBox_16(), and ScaleUVBox() functions all
contain the following expression:

  const int max_y = (src_height << 16);

where src_height is a positive int. This expression overflows if
src_height >= 32768.

Tracing the callers, we make sure ScalePlane(), ScalePlane_16(), and
UVScale() reject src_height < -32767 || src_height > 32767 as invalid
input. (These functions negate a negative src_height before calling a
function that executes expression src_height << 16.)

Although UVScale_16() do not execute the expression src_height << 16,
make the same change to UVScale_16() for consistency with UVScale().
