Renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + changed ImGuiIO layout.

Minor mostly inconsequential merges from Viewport + LoadIniSettingsFromMemory() entirely skip lines starting with ';'

Internals: Exposed SliderBehaviorT, DragBehaviorT, RoundScalarWithFormatT, SliderCalcRatioFromValueT. (#2036) ...

Renamed RoundScalarWithFormat -> RoundScalarWithFormatT.
Renamed SliderBehaviorCalcRatioFromValue -> SliderCalcRatioFromValueT
