+Once the key point of the animation are choosen (some scaling is
+likely to be needed to achieve good results) the strategy can simply
+move the slides linearly between points: I think this linearization
+will not be noted by the eye. 
+
+Animations should be put in some kind of class or module so that they
+can be easily added/changed.

+Note: if we want to do some rotations and translations with linear
+algebra a library such as Boost uBlas could be helpful.

+POPPLER_PAGE_TRANSITION_REPLACE
+-------------------------------
+
+Plain switch.
+
+
+POPPLER_PAGE_TRANSITION_SPLIT
+-----------------------------
+
+Some kind of page split. Think of having two halves of the page with
+complementary alpha channels.

+POPPLER_PAGE_TRANSITION_BOX
+---------------------------
+
+This can be mapped to the cube.
+
+
+POPPLER_PAGE_TRANSITION_FLY
+---------------------------
+
+This could be some slide fading while rapidly going towards the
+viewer.
+
+
+POPPLER_PAGE_TRANSITION_PUSH
+----------------------------
+
+Could be the opposite of fly.
+
+
+POPPLER_PAGE_TRANSITION_FADE
+----------------------------
+
+Normal fading

+The following transition codes are free for future usages:
