Slider UI fix: pointer inputs not adjusted for adaptive scaling

[marns]

With adaptive scaling active, transformCoordinates is required to bring pointer inputs into the correct slider space. Otherwise input pointer may be significantly off / remapped from visuals.

Fix: always transform pointer coordinates

Just for me to understand, the only change here is running the code even if the component's is 0, right?

[sebavan]

@marns, any repro of the bug it creates ?

[marns]

@RaananW right

@sebavan
Here's a repro before:
https://playground.babylonjs.com/#QZA0FG#2

and after:
https://playground.babylonjs.com/?snapshot=refs/pull/17968/merge#QZA0FG#2

Here you can see input is mapped to the middle 25% of the rendered slider
In my case it was mapping to last 25%
