wall: fix non-first abscissa of non-8-bit samples
The X and Y values are pixel coordinates in the potentially subsampled plane resolution. This must be converted to an octet offset as the type of the pixel plane pointer is pointer-to-uint8_t. So the X value must be multiplied by the sample size. The current code was instead rounding the value down to a multiple of the sample size. Bug reported by Philipp Marek on IRC. (cherry picked from commit 87733c50)
