void gimp_tile_cache_size (gulong kilobytes);
Sets the size of the tile cache on the plug-in side. The tile cache
is used to reduce the number of tiles exchanged between the GIMP core
and the plug-in. See also gimp_tile_cache_ntiles().
| kilobytes: | new cache size in kilobytes | 
void gimp_tile_cache_ntiles (gulong ntiles);
Sets the size of the tile cache on the plug-in side. This function
is similar to gimp_tile_cache_size() but allows to specify the
number of tiles directly.
If your plug-in access pixels tile-by-tile, it doesn't need a tile cache at all. If however the plug-in accesses drawable pixel data row-by-row, it should set the tile cache large enough to hold the number of tiles per row. Double this size if your plug-in uses shadow tiles.
| ntiles: | number of tiles that should fit into the cache |
