Detailed Description

Color filter that provides transformations to improve contrast for users with low vision.

Applies the following transformations in this order. Each of these can be configured using SkHighContrastConfig.

• Conversion to grayscale
• Color inversion (either in RGB or HSL space)
• Increasing the resulting contrast.

Calling SkHighContrastFilter::Make will return nullptr if the config is not valid, e.g. if you try to call it with a contrast outside the range of -1.0 to 1.0.
