    public abstract int convertToPixels(float value, String unit, boolean isHor, float refValue, ContainerWrapper parent, ComponentWrapper comp)

    Converts `value` to pixels.

    ###### Parameters

    - `value`: The value to be converted.

    - `unit`: The unit of `value`. Never `null` and at least one character.

    - `refValue`: @param refValue Some reference value that may of may not be used. If the unit is percent for instance this value is the value to take the percent from. Usually the size of the parent component in the appropriate dimension.

    - `isHor`: If the value is horizontal (`true`) or vertical (`false`).

    - `parent`: @param parent The parent of the target component that `value` is to be applied to. Might for instance be needed to get the screen that the component is on in a multi screen environment.

    May be `null` in which case a "best guess" value should be returned.

    - `comp`: The component, if applicable, or `null` if none.

    ###### Returns

    The number of pixels if `unit` is handled by this converter, `UnitConverter.UNABLE` if not.
