tint_fade(t, r, g, b, a) is misconfigured

[Alasdairbugs]

SuperTux Version

v0.6.3-1507-gc2e6b766d

System Information

win 11 64 bit

Expected Behavior

as per documentation tint_fade follows t, rgba

Actual Behavior

this is not the case, instead:

• the variable for time also controls blue
• the variable for blue also controls red

so its t+b, r, g, r+b, a

Steps To Reproduce Actual Behavior

• get a tilemap, place some lightmap white tiles, for ease' sake.
• get a lever, on switch is .tint_fade(0, 1, 1, 1, 1);
• make the off switch something else, but you will see that the first variable definitely controls at least TIME, because if you do 5, 0, 1, 1, 1 then it slowly changes colour
• and if you do 0, 1, 1, 1, 1 it becomes yellow, which means absence of blue. so it controls blue and time

repeat for the other mistake, doing 1, 1, 1, 0, 1 makes it go green. now green is the absence of two colours, red and blue. so the fourth variable also controls two things.
