Subject: swscale: don't use planar output functions to write to NV12/21.

This prevents a crash when converting to NV12/21 without the bitexact
flags enabled.

Subject: swscale: split yuv2packedX_altivec in smaller functions.

This will likely lead to a considerable performance boost,
since it removes a branch from the inner loop. Part of the
Great Evil Plan to simplify swscale.

From 13a099799e89a76eb921ca452e1b04a7a28a9855 Mon Sep 17 00:00:00 2001

Subject: swscale: change prototypes of scaled YUV output functions.

Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

+     * - Scaling is done using only 7bit instead of 14bit coefficients.
+     * - You can use no more than 5 input pixels to produce 4 output
+     *   pixels. Therefore, this filter should not be used for downscaling
+     *   by more than ~20% in width (because that equals more than 5/4th
+     *   downscaling and thus more than 5 pixels input per 4 pixels output).
+     * - In general, bilinear filters create artifacts during downscaling
+     *   (even when <20%), because one output pixel will span more than one
+     *   input pixel, and thus some pixels will need edges of both neighbor
+     *   pixels to interpolate the output pixel. Since you can use at most
+     *   two input pixels per output pixel in bilinear scaling, this is
+     *   impossible and thus downscaling by any size will create artifacts.
