Made clearscreen a Video member for access to the surface pixels.

Medivo guardian now also destroys blocks that are hit by the spike, and removes itself from the scene when he's killed. This nearly completes the guardian. The overlap method still has to be implemented, and the end sequence could still be closer to what the original game does.

guardians.cpp
*) Changed step method of MedGuardian.

Fixed the hopping in the medivo boss. The previous version made the boss float over the blocks it was supposed to destroy occasionally. Now the spike always touches them ever so slightly. Note that the blocks are not being destroyed yet. That's on the agenda for tomorrow ;-).

guardians.cpp
*) Changes the step method to make the hopping in the second stage of the boss more reliable.

Various changes to implement medivo boss behavior. Medivo boss behavior isn't finished yet but works up until the spikes.

anim.cpp, anim.h
*) Changes in animations to properly support accessory positions.
*) Changes in animations to properly support accessory shooting positions.

bullet.cpp, bullet.h
*) New constructor for a custom bullet starting position

levelframe.cpp
*) Support medivo boss

event.cpp, eventframe.cpp
*) Small changes in getAnim()
*) Small changes in step method

guardians.cpp, guardians.h
*) Made the eight shape in the first stage.
*) Made the jumping behavior, but this doesn't work as it should yet.
*) Did not implement the overlap method yet.

Fixed menu and player size in Bonus levels. The viewW/viewH variables are now only used with ordinary levels (which have the panel).

Corrected shooting positions of most shooting enemies. (E.g. the turtle tanks in fanolint and technoir did not work correctly.) Bullets will now shoot from the position that was set in the attack animation.

sprite.h, sprite.cpp
*) Changed draw method to include a parameter to enable or disable the drawing of sprite offsets (bullets do not use these offsets). The default behavior is to add the offset. 

bullet.cpp
*) Changed the draw method to disable sprite offsets, using the parameter that was mentioned earlier.
*) Slightly changed the way the y position of the bullet is determined in the event constructor.

Okay, with this update I am going to declare special behaviors fixed. Even though you might not believe me, because this is the fourth time I am making such a claim. This time I'm dangerously close to what the real game does ;-)

anim.cpp
*) Changed the getOffset accessor to add the default 32 pixel offset if it should be there.

bridge.cpp
*) Because of the change in anim.cpp I could remove the default 32 pixel offset I added earlier.

event.h, event.cpp
*) Changed the overlap method to include the offset if necessary.

eventframe.cpp
*) Changed the step method and removed the default 32 pixel offset I added earlier.
*) Changed the draw method slightly so when offsets should be ignored, that actually is the case.

eventframe.cpp
*) Explosive effect now is more random
*) Changed positioning of special behavior again slightly
