Modify sample buffer size for larger displays

BZ: 146848

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.
