Comment(by wenzeslaus):
In attachment png_rendering_pil_composition.diff you can see some changes
which are necessary for rendering PNG (instead of PPM) and composing of
images in Python using PIL (instead of g.pnmcomp).
It is not completely working code. It is only experiment to see if this
can be faster.
The answer is no. I don't have any numbers but user experience is
completely the same.
Files are much smaller and there is one file less (thanks to composing in
Python) but during zooming/panning the most of the time is spent with disk
IO. (Tested on Ubuntu 10.04.)
But we can output binary data to stdout and read them in Python directly.
This would avoid disk IO. What do you think about using stdout instead of
a file in case of d.* modules?
