[Engine] Black Baground on section resize event

[Alucard648]

Engine 0.3.4.0 built 01.02.2021

Whenever the section was resized beyond it`s initial dimensions by event it renders black backround outside default dimensions. Similar to issue with Xtech TheXTech/TheXTech#42

Test level: https://disk.yandex.ru/d/WW0aPqMxZjDPpg

Expected behavior
It depends on background settings. it maybe:

• tiled backround
• repeat edge pixels with gradient fading to specific color

I'd still suggest that since this doesn't occur with levels already at a larger size that the game should compensate by accounting for max possible resizes based on event data in the level, in order to get a normal looking background

Section can be resized not only by events, but also by scripts.

That... could get substantially trickier to account for O.o

The black lower than section is a way to avoid the parallax distortion when a player goes lower than the actual section boundary. If change the section size together with the background hot spot, the result would look weird when the background parallax will change itself. Do you suggest making some sort of the gradient from the lowerest row color into the black like the similar case at TheXTech? However, I should apply the left-right background algorithm from the PGE Engine into TheXTech to resolve the damn that appears when you do resize the section into the left at the left boundary. I still have the illustration of this damn at my archive, but I can't find it yet...
