void adw_squeezer_set_xalign ( AdwSqueezer* self, float xalign )
Sets the horizontal alignment, from 0 (start) to 1 (end).
This affects the children allocation during transitions, when they exceed the size of the squeezer.
For example, 0.5 means the child will be centered, 0 means it will keep the start side aligned and overflow the end side, and 1 means the opposite.
