perfectly fine, as the bool toggle fairly rarely. If you have on a touch device, you might find use for an early call to NewFrameUpdateHoveredWindowAndCaptureFlags().
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 targetted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)

Q: How can I display an image? What is ImTextureID, how does it works?
A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function.
