-/* Defines the buffer size for sample pixel indexes, used in the sample proc function calls.

- * for the performance of SIMD optimizations.
- * A display in portrait mode, with a width of 720 pixels, requires a buffer size of at least 721
- * to run uninterrupted in the more basic operations.
- * (Formula: Width + 1 for 'scale/translate with filter' procs.
- *  See description of SkBitmapProcState::maxCountForBufferSize for more information.)
