nMaxConvSize

Maximum size for a conventional bitmap (default is $7FFFFFFF). Any bitmaps with a size bigger than this will be allocated as tiled.

If this parameter is >0, then it represents the maximum size in bytes.

If the parameter is <0, then it represents the maximum size in percentage of the total memory (physical and swap).

Values less than –100 are not allowed.

This parameter is ignored if uFlags does not contain MEM_MAXCONVSIZE.
