Rotation off of zero (0) degrees only occurs when dragging outside
the bounding box (rectangle around the width/height) of the stamp.
No longer warping mouse to the right of the stamp, to cause it to
default to zero degrees. (The mouse being at the center of the
stamp now causes this, per the above change.)
Motivation - Placing stamps on mobile (touchscreen) was difficult
and non-intuitive. Now, you can at least double-tap the same
spot on the screen to position, and then place (without rotation)
the stamp. It's still not perfect, and I think a UI option to
enable/disable stamp rotation (leaving it off by default) is needed.
e.g. if the aspect ratio of the template/starter is wider than
that of the canvas, and "autoscale=vertical" (or "=both")
is specified, before it would chop the top and bottom of the
image off, displaying the vertical center of it on the canvas.
Now you can ask it to gravitate towards the top or bottom, if they
have content that's of higher significance than the opposite side.
h/t Pere & Albert for the suggestion.
TODO - Document, set some suitable defaults for images we ship.
Now possible to set scaling and smearing options for
each starter or template image. A ".dat" file can be
created which describes whether it's okay to scale and crop
the image's top/bottom and/or left/right, and if not both,
whether to smear the sides of the starter/template to the
edges of the canvas (the prior behavior, and the default),
or use a specific solid color background.
Once finished, will close

Still to do:
+ Document
+ Remove debugging printf()s (change to DEBUG_PRINTF()?)
+ Add files for starters & templates that ship with Tux Paint
+ Test!
Convert the image into circular or ray brushstrokes.
