Wait a minute. Pleass explain me what you mean in "gen-topologies" and 
"iso-rectangular maps".

I implement new position code becouse I want have "spheric maps" and my code 
let me this.

Yes it is hard-coded but I plan make it more configurable.
For now if you want another size of tiles just unrem first two lines in this 
function and rem anothers lines.

In future I want add (var) accelerators in place ...<< 5; and ...< 4;

( ...<< WIGHT_ACCELL; ...<< HIGHT_ACCELL; ) that are loaded with tilespec.

That depend on yours resolution and CPU. I have p200MMX and in res. above 
800x600 I can see this speedup. ( I use this code in drawing fuctions ).

PS. I'm very pleased that somebody read my code :)
