When trying to detect if the mouse is hovering over an nk_image, it detects the image right under the actual image.
I believe that nk_widget bounds returns a nk_rect where the x and y correspond to the x and y coordinates of the bottom left corner of the widget
While the nk_input_is_mouse_hovering_rect thinks that rect's x and y coordinates correspond to the top left corner.
I'm not entirely sure if the topleft or the bottomleft as xy coordinates is true, so I'm not really sure which one should be fixed.
But I thought this would be useful to point out.
