MaskMergeMode

Determines whether to set elements that are not selected by mask to 0 in dst. The options are as follows:

• MaskMergeMode::UNKNOWN: used when the conversion type does not support MaskMergeMode.
• MaskMergeMode::ZEROING: Elements that are not selected by mask are set to 0 in dst.
• MaskMergeMode::MERGING: Elements that are not selected by mask keep their original values in dst.
