/*
* This file contains scaled bilinear scanline functions implemented
* using older siarhei's bilinear macro template.
*
* << General scanline function procedures >>
* 1. bilinear interpolate source pixels
* 2. load mask pixels
* 3. load destination pixels
* 4. duplicate mask to fill whole register
* 5. interleave source & destination pixels
* 6. apply mask to source pixels
* 7. combine source & destination pixels
* 8, Deinterleave final result
* 9. store destination pixels
*
* All registers with single number (i.e. src0, tmp0) are 64-bits registers.
* Registers with double numbers(src01, dst01) are 128-bits registers.
* All temp registers can be used freely outside the code block.
* Assume that symbol(register .req) OUT and MASK are defined at caller of these macro blocks.
*
* Remarks
* There can be lots of pipeline stalls inside code block and between code blocks.
* Further optimizations will be done by new macro templates using head/tail_head/tail scheme.
