+  * Technical note : explaining how the blitter works.
+  *
+  *   The blitter is used to "draw" a given source bitmap into
+  *   a given target bitmap.
+  *
+  *   The function called 'compute_clips' is used to compute clipping
+  *   constraints. These lead us to compute two areas :
+  *
+  *   - the read area : is the rectangle, within the source bitmap,
+  *                     which will be effectively "drawn" in the
+  *                     target bitmap.
+  *
+  *   - the write area : is the rectangle, within the target bitmap,
+  *                      which will effectively "receive" the pixels
+  *                      from the read area
+  *
+  *   Note that both areas have the same dimensions, but are
+  *   located in distinct surfaces.
+  *
+  *   These areas are computed by 'compute_clips' which is called
+  *   by each blitting function.
+  *
+  *   Note that we use the Y-downwards convention within the blitter
