bad handling of bool's

you have parameters that use nk_bool, like for the nk_input_button, however you are handling those as int's instead... and in some places even comparing against "true" if (down==1 && ...) ... which is a bug and should be if (down && ...) (for the click on button release) and similar logic for the dragging of move/size)

so passing anything but 1 to that to cause those to fail.

Search the repository for nk_input_button, nk_bool, and comparisons against 1 or true, then inspect the related button-release and move/size dragging logic. Confirm that boolean values other than 1 are handled correctly and validate the affected input behaviors.
