Internals: Breaking: ImRect() default constructor initializes all fields with 0.0f

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.

documented (can only unreserve from the last reserve call). If you suspect you ever
used that feature before, #define IMGUI_DEBUG_PARANOID in imconfig.h to catch existing
calls. [@ShironekoBen]
- 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.
Other Changes:
- Inputs: Added ImGuiMouseButton enum for convenience (e.g. ImGuiMouseButton_Right=1).
