rozenmad edab2be4c7 Added grid span feature, fixes
- Grid span feature
- Added offset from parent to update each element (for correct positioning relative to each parent)
- OnClick event rework
- Multichoice: new function GetChoiceIndex
- Added positioning of items in the grid using the align parameter in AddItem
- Correct positioning of multichoice-arrow image
- Fixed stencil test for list
- Fixed a bug that can trigger OnClick events again, even if the mouse cursor is not already hovering over the object
- Fixed a bug where "backspace" leads to an incorrect positioning of the entry if the text is overflowed 'textinput' element
