GPUImageChromaKeyBlendFilter -> ChromaKeyBlend.glsl - remained uniform vec3 colorToReplace, uniform sampler2D inputImageTexture, uniform sampler2D inputImageTexture2; verify final parameters in GPUImageColorBlendFilter -> ColorBlend.glsl, GPUImageDivideBlendFilter -> DivideBlend.glsl, GPUImageHardLightBlendFilter -> HardLightBlend.glslб GPUImageHueBlendFilter -> HueBlend.glsl, GPUImageLuminosityBlendFilter -> LuminosityBlend.glsl, GPUImageOverlayBlendFilter -> OverlayBlend.glsl, GPUImageSaturationBlendFilter -> SaturationBlend.glsl in android-gpuimage(these filters have conditional constructions and some calculations); GPUImageMixBlendFilter -> MixBlend.glsl in android-gpuimage (don't understand where to copy the code)
