bug fix: float precision overflow in IM_NORMALIZE2F_OVER_ZERO
when added vertices are particularly dense or close together, sometimes the resulting lines will crack, flicker, or even cover the entire screen, causing the screen to flicker Since a root-splitting calculation will be performed later, 0.001 is appropriate affected functions: AddPolyline, AddConvexPolyFilled

// On AddPolyline() and AddConvexPolyFilled() we intentionally avoid using ImVec2 and superfluous function calls to optimize debug/non-inlined builds.

// - Those macros expects l-values and need to be used as their own statement.

// - Those macros are intentionally not surrounded by the 'do {} while (0)' idiom because even that translates to runtime with debug compilers.
