+  Notes
+  
+  This is one of the most critical parts of u8glib. It must be fast, but still reliable.
+  Based on the intersection program (see tools folder), there is minimized version of
+  the condition for the intersaction test:
+    minimized version
+    ---1----0 1             b1 <= a2 && b1 > b2
+    -----1--0 1             b2 >= a1 && b1 > b2
+    ---1-1--- 1             b1 <= a2 && b2 >= a1
+  It includes the assumption, that a1 <= a2 is always true (correct, because
+  a1, a2 are the page dimensions.
+
+  The direct implementation of the above result is done in:
+  uint8_t u8g_is_intersection_boolean(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1)
+  However, this is slower than a decision tree version:  
+  static uint8_t u8g_is_intersection_decision_tree(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1) 
+  Also suprising is, that the macro implementation is slower than the inlined version.
+  
+  The decision tree is based on the expansion of the truth table.
