QScreenRayCaster trigger y parameter needs to be "inverted": by design or bug?

[uani]

the trigger method of a QScreenRayCaster needs to receive the y-ccordinate of the mouse pointer as subtracted from the viewport height.

I would have expected a screen ray caster to take a possible OGL different coordinate system origin position into account.

Thus: bug or by design?

@uani screen related protocols does increase Y from the top by convention.

@e2002e yes, this is how the mouse pointer y coordinate is delivered but when I use it to screenraycast it hits on the opposite vertical side of the entity.

I subtract the mouse pointer y from the viewport height now to have a QScreenRayCast hit as expected.
