+ 3.1.0
+
+ Description:
+ Before 3.1.0, custom elements that "change when pushing" changed directly
+ after the player started pushing them (until then handled in "DigField()").
+ Since 3.1.0, these custom elements are not changed until the "pushing"
+ move of the element is finished (now handled in "ContinueMoving()").
+
+ Affected levels/tapes:
+ The first condition is generally needed for all levels/tapes before version
+ 3.1.0, which might use the old behaviour before it was changed; known tapes
+ that are affected are some tapes from the level set "Walpurgis Gardens" by
+ Jamie Cullen.
+ The second condition is an exception from the above case and is needed for
+ the special case of tapes recorded with game (not engine!) version 3.1.0 or
+ above (including some development versions of 3.1.0), but before it was
+ known that this change would break tapes like the above and was fixed in
+ 3.1.1, so that the changed behaviour was active although the engine version
+ while recording maybe was before 3.1.0. There is at least one tape that is
+ affected by this exception, which is the tape for the one-level set "Bug
+ Machine" by Juergen Bonhagen.

+ Summary of bugfix/change:

+ Description:
+ Before 3.1.1, when "block last field when moving" was enabled, the field
+ the player is leaving when moving was blocked for the time of the move,
+ and was directly unblocked afterwards. This resulted in the last field
+ being blocked for exactly one less than the number of frames of one player
+ move. Additionally, even when blocking was disabled, the last field was
+ blocked for exactly one frame.
+ Since 3.1.1, due to changes in player movement handling, the last field
+ is not blocked at all when blocking is disabled. When blocking is enabled,
+ the last field is blocked for exactly the number of frames of one player
+ move. Additionally, if the player is Murphy, the hero of Supaplex, the
+ last field is blocked for exactly one more than the number of frames of
+ one player move.

+ GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
+
+ When using an animation frame delay of 1 (this only happens with
+ "sp_zonk.moving.left/right" in the classic graphics), the default
+ (non-moving) animation shows wrong animation frames (while the
+ moving animation, like "sp_zonk.moving.left/right", is correct,
+ so this graphical bug never shows up with the classic graphics).
+ For an animation with 4 frames, this causes wrong frames 0,0,1,2
+ be drawn instead of the correct frames 0,1,2,3. This is caused by
+ "GfxFrame[][]" being reset *twice* (in two successive frames) after
+ an element change: First when the change delay ("ChangeDelay[][]")
+ counter has reached zero after decrementing, then a second time in
+ the next frame (after "GfxFrame[][]" was already incremented) when
+ "ChangeDelay[][]" is reset to the initial delay value again.
+
+ This causes frame 0 to be drawn twice, while the last frame won't
+ be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
+
+ As some animations may already be cleverly designed around this bug
+ (at least the "Snake Bite" snake tail animation does this), it cannot
+ simply be fixed here without breaking such existing animations.
+ Unfortunately, it cannot easily be detected if a graphics set was
+ designed "before" or "after" the bug was fixed. As a workaround,
+ a new graphics set option "game.graphics_engine_version" was added
+ to be able to specify the game's major release version for which the
+ graphics set was designed, which can then be used to decide if the
+ bugfix should be used (version 4 and above) or not (version 3 or
+ below, or if no version was specified at all, as with old sets).
+
+ (The wrong/fixed animation frames can be tested with the test level set
+ "test_gfxframe" and level "000", which contains a specially prepared
+ custom element at level position (x/y) == (11/9) which uses the zonk
+ animation mentioned above. Using "game.graphics_engine_version: 4"
+ fixes the wrong animation frames, showing the correct frames 0,1,2,3.
+ This can also be seen from the debug output for this test element.)
