*
* Where:
* dst - destination scanline buffer for storing results
* mask - mask buffer (or single value for solid mask)
* src_top, src_bottom - two source scanlines
* width - number of pixels to process
* weight_top - weight of the top row for interpolation
* weight_bottom - weight of the bottom row for interpolation
* vx - initial position for fetching the first pair of
* pixels from the source buffer
* unit_x - position increment needed to move to the next pair
* of pixels
* max_vx - image size as a fixed point value, can be used for
* implementing NORMAL repeat (when it is supported)
* zero_src - boolean hint variable, which is set to TRUE when
* all source pixels are fetched from zero padding
* zone for NONE repeat
*
* Note: normally the sum of 'weight_top' and 'weight_bottom' is equal to
* BILINEAR_INTERPOLATION_RANGE, but sometimes it may be less than that
* for NONE repeat when handling fuzzy antialiased top or bottom image
* edges. Also both top and bottom weight variables are guaranteed to
* have value, which is less than BILINEAR_INTERPOLATION_RANGE.
* For example, the weights can fit into unsigned byte or be used
* with 8-bit SIMD multiplication instructions for 8-bit interpolation
* precision.
