// TUTORIAL: input_numeric widgets — type the number, optionally with
// +/- step buttons.
//
//   input_float(IDENT, (text = "..", step = 0.0f, step_fast = 0.0f,
//                       format = "%.3f", flags = ImGuiInputTextFlags....))
//   input_int(IDENT, (text = "..", step = 1, step_fast = 100,
//                     flags = ImGuiInputTextFlags....))
//   input_double / input_float2/3/4 / input_int2/3/4 — same shape;
//   scalar / vector / double-precision variants.
//
// Scalar forms get step / step_fast args — non-zero shows ImGui's +/-
// buttons, click = step, ctrl-click = step_fast. Vector forms (2/3/4)
// have no step args — the buttons would crowd the row.
//
// Default int step = 1 / step_fast = 100; float defaults are 0.0 (no
// buttons). input_double defaults to 0.0lf (no buttons) with format
// "%.6f" for the extra precision.
