For Ventana TIFF and Philips TIFF, see the undocumented properties 
openslide.level[n].tile-width and openslide.level[n].tile-height. These 
properties do not exist for Ventana BIF because that format doesn't 
place tiles on a regular grid, so the tile size isn't very useful 
without a lot of detailed information about the layout of the slide.

Those properties exist because some applications may want to use them 
for performance optimization, but are undocumented because I'm not 
entirely convinced they're a good idea.  How do you plan to use the tile 
size information?
