InputText: render currently edited buffer from the internal buffer, toward #701

InputText, ImGuiTextFilter: using strncpy instead of printf("%s").

Wrapped text: fixed incorrect testing for negative wrap coordinates, they are perfectly legal. (#706)

ColorEdit4(): better preserve inputting value out of 0..255 range, display then clamped in Hexadecimal form

Fixed minor text clipping issue in window title for when using font straying above usual line (#699)

Member variable name renamed "ID" "Id" for casing consistency

TextUnformatted() fixed clipping bug in the large-text path when horizontal scroll has been applied (#692, #246)

ImDrawList: Fixed a (rarely occuring) bug with merging with previous command + unnecessary OverlayDrawList command

Fixed TextWrapped() override wrap position is one is already set (#690)

Fixed minor bug introduced in 45dacbf (#682) ...

Actually minor because nobody uses that value. Still a terrible
bug.
