Modify sample buffer size for larger displays.
Increases the intermediate buffer size for sample pixel indexes,
used in the sample proc function calls. If the operation is bigger
than the buffer it's split into multiple calls, creating overhead.
This would especially impact the performance of SIMD optimizations.
Also, aligns the start address of the buffer to 16 bytes, to enable
more efficient SIMD optimizations.
