&fnlFractalGain should be &fnlDomainWarpFractalGain

[Sabrejack]

FastNoiseLite/WebPreviewApp/main.cpp

Line 246 in 8e296ac

 if (ImGui::DragFloat("Gain", &fnlFractalGain, 0.01f)) 

Slider is not functioning properly in the demo, I believe this line is meant to be &fnlDomainWarpFractalGain

Thanks!
