Fix for tilingsprite destroy ...

When a tiling sprite was destroyed the setter was called, which would
set the point value to null. This gave an error while Point.copy does
not like null values.

My fix is to bypass the setters and set the object properties to null.
I’ve added the uvTransform also.

clear lint warnings

Found problems in PIXI.Sprite too, added a test

TilingSprite BaseTexture resolution ...

I ran into a problem if the base texture resolution is not 1 and the renderer is not WebGL. The resolution auf the base texture is nowhere considered. This is how i solved it. The solution is probably not the best...

Giant tilingSprite refactoring. ...

1. Rotated and trimmed textures are allowed
2. "full" textures use simple shader if they have WRAP_MODE.REPEAT

4. TilingSprite now has tileTransform which applies to the "zero tile" like if its been a child

added getLocalBounds

Huge refactor to match a new shiny eslint file.
