It doesn't actually capture your screen, but rather saves the Cairo
surface to an image. The path to the image and some other options
can also be configured in the config file.
By default, Print Screen can be pressed in Normal mode with no modifier
to take a screenshot. The default location is the user's home directory,
and the file has a date attached to it. Of course, this can be changed
as well.
The fullscreen functionality is kind of cool, but adds a lot of code and
as commit history has shown, plenty of bugs and extra required testing.
I may reimplement this later in a less bad manner. Note that the
fullscreen behavior can be achieved by simply increasing image size to
the max. spmenu will let you do that.
Fixes issue #9
This commit also adds MASSIVE speed improvements to image drawing, due
to code cleanup. There are still a *few* issues to resolve, one is
X11 related, and one is caused by alpha/blending.
