[Pixman] [PIXMAN][PATCH 6/6] Bilinear REPEAT_NORMAL source line extension for too short src_width

[Taekyun Kim]

To avoid function call and other calculation overhead, extend source
scanline into temporary buffer when source width is too small.
Temporary buffer will be repeatedly accessed, so extension cost is
very small due to cache effect.
