I've attached a patch for an issue with absolute input devices like
Wacom tablets and touchscreens in fullscreen. The issue is actually
an SDL bug, but there is a pretty simple workaround, which is
described pretty thoroughly in Debian bug 559615 . Essentially,
SDL implements infinite scrolling in a way which doesn't play nice
with these input devices. Disabling this behavior is as simple as:
The patch adds setting this environment variable to the Aquaria binary
to avoid the need for a wrapper script.
This may fix bug 4608  based on the symptoms described there,
though I haven't confirmed as I neither own a Mac nor have access to a
Wacom tablet at the moment. I have tested this patch under Linux
using a Lenovo S10-3t touchscreen netbook.
I'm hoping that someone else can test this on the platforms I don't
have access to and confirm there are no regressions.
