The FSanitizedGradient class provides a mean of storing gradients in various formats, with constraints the help in rasterizing them more efficiently than their non-Sanitized counterparts, which are meant for modification and editing. More...

Detailed Description

FSanitizedGradient can have a single or no color. Steps are in [0;1]. Interpolation is linear in the preferred format.
