nTileSize
The size of the tile for tiled bitmaps (default 0). Pass a value smaller than nMaxConvSize.
All bitmaps with a size smaller than nTileSize will be allocated as conventional. (A tiled bitmap of a size smaller than nTileSize would consist of only small tile, which is the equivalent of the conventional bitmap).
If nTileSize is 0, then LEADTOOLS will pick a default size for the tile. (Currently it is 16MB)
The tiles will be smaller than this value and will be a complete number of rows. No rows will be split between tiles.
Values less than 0 are not allowed.
This parameter is ignored if uFlags does not contain MEM_TILESIZE.
