Hi

there you have a script. Blendmodes only work with pygame1.8. Users 
using pygame1.7 can start the script, but should not change the 
blendmode pressing 'm'.

Perhaps I have done something wrong, please correct any mistake you 
find. Or perhaps I have forgotten an interesting case.

Results:

rotate() screws up on normals surfaces and surfaces with per surface alpha.

rotozoom() screws up all except surfaces with per pixel alpha

Blendmodes do not respect colorkey nor per pixel alpha. I do not know if 
this is intentional.

rotozoom fills the space in with black, therefore you will not see any 
difference in blendmodes 'add' or 'sub' (because adding 0 or subtracting 
0 gives the same number).

An is there a reason why colorkey and per pixel alpha are mutual 
exclusive? (is that a constraint from SDL?)
