// - ImGuiInputTextFlags_CallbackCharFilter: return 1 if the character is not allowed. You may also set 'EventChar=0' as any character replacement are allowed.
// - ImGuiInputTextFlags_CallbackCharFilter: return 1 if the character is not allowed. You may also set 'EventChar=0' as any character replacement are allowed.
// - ImGuiInputTextFlags_CallbackResize: BufTextLen is set to the new desired string length so you can allocate or update the size on your side of the fence. No need to initialize new characters or zero-terminator as InputText will do it.
// - ImGuiInputTextFlags_CallbackResize: notified by InputText() when the string is resized. BufTextLen is set to the new desired string length so you can update the string size on your side of the fence. You can also replace Buf pointer if your underlying data is reallocated. No need to initialize new characters or zero-terminator as InputText will do it right after the resize callback.

// - To modify the text buffer in a callback, prefer using the InsertChars() / DeleteChars() function. InsertChars() will take care of calling the resize callback if necessary.
// - If you know your edits are not going to resize the underlying buffer allocation, you may modify the contents of 'Buf[]' directly. You need to update 'BufTextLen' accordingly (0 <= BufTextLen < BufSize) and set 'BufDirty'' to true so InputText can update its internal state.
