This is normally called by Render(). You may want to call it directly if you want to avoid calling Render() but the gain will be very minimal.

This duplicates some of the logic in UpdateFontsNewFrame() which is a bit chicken-and-eggy/tricky to extract due to variety of codepaths and possible

GLFW doesn't allow to distinguish Mouse vs TouchScreen vs Pen. Add support for Win32 (based on imgui_impl_win32), because we rely on _TouchScreen info

Preload all glyph ranges for legacy backends. This may lead to multiple texture creation which might be a little slower than before.
