+/* version change history:
+ *
+ * 0.1: the original version
+ *
+ * if a waypoint goes from -179 to 179 degrees, that is a 2
+ * degree change. there's no way to express a 720 degree
+ * rotation with a single pair of waypoints
+ *
+ * 0.2: svn r1227
+ *
+ * angles no longer wrap at -180 degrees back to 180 degrees; if
+ * a waypoint goes from -179 to 179 degrees, that is a rotation
+ * of 358 degrees. loading a version 0.1 canvas will modify
+ * constant angle waypoints to that they are within 180 degrees
+ * of the previous waypoint's value
+ *
+ * the 'straight' blend method didn't used to work properly. it
+ * didn't work at all on transparent pixels in layers other than
+ * the PasteCanvas layer. for example, the examples/japan.sifz
+ * file has a red circle (straight, amount=1.0) on top of a
+ * striped conical gradient. if 'straight' was working, the
+ * conical gradient would be entirely obscured by the circle
+ * layer (even by its transparent pixels)
+ *
+ * 0.3: svn r1422
+ *
+ * the 'straight' blend method was fixed. loading a version 0.2
+ * or older canvas will replace the 'straight' blend method in
+ * non-pastecanvas layers with 'composite', unless they're
+ * completely transparent, in which case it will replace them
+ * with an 'alpha over' blend instead. Images like
+ * examples/logo.sifz use transparent straight blends to do
+ * masking, which no longer works now that 'straight' blending is
+ * fixed.
+ *
+ * Tangent lengths calculated by the "Segment Tangent" and "BLine
+ * Tangent" ValueNodes were scaled by a factor of 0.5.
+ *
+ * 0.4: svn r1856
+ *
+ * Stop scaling tangents by 0.5.
+ *
+ * 0.5: svn r1863
+ *
+ * Added "offset", "scale", and "fixed_length" links to the
+ * "BLine Tangent" ValueNode.
+ *
+ * 0.6: svn r2067
+ *
+ * Added "scale" link to the "BLine Width" ValueNode in svn r1872.
+ *
+ * Added "loop" link to the "Gradient Color" ValueNode in svn r1901.
+ *
+ * 0.7: svn r2315
+ *
+ * Added "loop" link to the "Random" ValueNode in svn r2315.
