Replace manual flooring with IM_FLOOR() macro. (#2850)

Browse Source 
Macro is used to ensure that flooring operation is always inlined even in debug builds. __forceinline does not force inlining in /Od builds with MSVC.

(cherry picked from commit bc165df6fd7969605bbc07b8a6d3d28f9109e8f3)

They tell you if Dear ImGui intends to use your inputs. When a flag is set you want to hide the corresponding inputs from the

Note: Text input widget releases focus on "Return KeyDown", so the subsequent "Return KeyUp" event that your application receive will typically
have 'io.WantCaptureKeyboard=false'. Depending on your application logic it may or not be inconvenient. You might want to track which key-downs
were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)
Q: How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display)
