Browse Source 
Instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). Previous behavior was designed for adding into a bounding box but rarely relied on and not worth it.

- imgui_internal.h: changed ImRect() default constructor initializes all fields to 0.0f instead
of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by
adding multiple points into it, you may need to fix your initial value.
