No... I'd like to have a hardware scaler pretty soon though. Right now, 
the only way to access a hardware scaler is by going through GEM using 
[#to_pix]. In the case of SDL, I think that it uses a combination of 
changing the video mode and using hardware scaling and black borders, with 
a preference on avoiding hardware scaling. But I don't know much about

Then it means that SDL's full screen command does not work on OSX.

This page says it only works in X11 : 
And I don't think you can make SDL go through X11 on OSX, and I wouldn't 
bet that OSX's X11 supports the fullscreen commands.

Strange, I thought that it would only say that for much bigger windows, 
such as 4096x3072 and such. Maybe OSX has much lower limits of memory size 
for shmget() than Linux has. I wouldn't know how to increase that.

BTW, you have to swap the arguments to out_size. The number of rows 
usually comes before the number of columns in GridFlow.

I don't know why that would happen.

Also, I never use out_size because as it is, GridFlow always resizes the 
window to the same size. I expect that out_size will become more important 
if I enable hardware scaling in a future version.
