Another fix for gate drawing bug

[Falcury]

This is another version of the fix for the gate drawing bug that occurs when multiple gates are stacked on top of each other. Calls draw_tile_anim_topright() to redraw the erased part of the gate. Luckily, the animation when the gate opens still works correctly this way.

I also tried to restore FIX_BIGPILLAR_CLIMB, but as it says in bugs.txt and in the code comments, "The current fix causes glitches you can see on bug_chomper.PNG and bug_climb.PNG". Unfortunately I couldn't find back these images, so I can't really verify that the glitches are fixed... But, this may be a possible fix...?

// seg008:1E3A
void __pascal far draw_floor_overlay() {
#ifdef FIX_BIGPILLAR_CLIMB
    if (tile_left != tiles_0_empty) {
        // Bug: When climbing up to a floor with a big pillar top behind, turned right, Kid sees through floor.
        // The bigpillar_top tile should be treated similarly to an empty tile here.
        if (!fix_bigpillar_climb || (tile_left != tiles_9_bigpillar_top)) {
            return;
        }
    }
#else
    if (tile_left != tiles_0_empty) return;
#endif

I never published those images, sorry about that... Here they are: They're from 2014 May, when the guards did not have colors yet...

Thank you for the screenshots! I was able to reproduce the glitches. I added a second commit with a fix for the big pillar drawing bug, where the glitches do not occur.

By the way, I noticed while testing that there is another drawing bug with chompers (in the original game):
