// The value ranges from 0.0 (sharp mask edge) to 1.0 (smooth mask edge). By default, the property is set to 0.0.
property real maskSpreadAtMax: 0
// This property switches the mask to the opposite side; instead of masking away the content outside maskThresholdMin and maskThresholdMax, content between them will get masked away.

// By default, the property is set to false.
property bool maskInverted: false
// This property defines a multiplier for extending the blur radius.
//
// The value ranges from 0.0 (not multiplied) to inf. By default, the property is set to 0.0. Incresing the multiplier extends the blur radius, but decreases the blur quality. This is more performant option for a bigger blur radius than BLUR_HELPER_MAX_LEVEL as it doesn't increase the amount of texture lookups.

// Note: This affects to both blur and shadow effects.
