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.
