Floating-point pipeline and plugins

CINELERRA-GG runs internally in 32-bit floating-point and thus can read and process values outside the range (0 - 1.0f ) (illegal values, they need the final conforming step to comply with the legal values). However, there are plugins and tools that can introduce clipping that must be taken into account to keep the whole pipeline which preserves the original values. The limited plugins are: Blur; Color 3 Way (partially); Color Space; Foreground; Histogram (partially); Histogram Bezier; Title; Videoscope (partially).
