DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types. We are reusing function instances for larger types to reduce code size. (#643, #320, #708, #1011)

Other Changes:
|
||||
|
||||
- Nav: Fixed a tap on AltGR (e.g. German keyboard) from navigation to the menu layer.
|
||||
- DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types.
|
||||
We are reusing function instances for larger types to reduce code size. (#643, #320, #708, #1011)
|
||||
- InputInt, InputFloat, InputScalar: Fix to keep the label of the +/- buttons centered when
|
||||
style.FramePadding.x is abnormally larger than style.FramePadding.y. Since the buttons are
|
||||
meant to be square (to align with e.g. color button) we always use FramePadding.y. (#2367)
