Subject: screenshot: add png compression setting

The default compression setting is 7, which is hopefully a good balance
between speed of compression, and resulting file sizes. The maximum png
compression will be very slow even on fast computers. On the other hand,
the lowest compression setting produces files of several MB size with
normal video resolutions, which should be avoided as well.
