示例1: ApplyBase
/// <summary>
/// Provides a default implementation for performing dst = F(dst, src) or F(src) over some rectangle
/// of interest. May be slightly faster than calling the other multi-parameter Apply method, as less
/// variables are used in the implementation, thus inducing less register pressure.
/// </summary>
/// <param name="dst">The Surface to write pixels to, and from which pixels are read and used as the lhs parameter for calling the method <b>ColorBgra Apply(ColorBgra, ColorBgra)</b>.</param>
/// <param name="dstOffset">The pixel offset that defines the upper-left of the rectangle-of-interest for the dst Surface.</param>
/// <param name="src">The Surface to read pixels from for the rhs parameter given to the method <b>ColorBgra Apply(ColorBgra, ColorBgra)</b>.</param>
/// <param name="srcOffset">The pixel offset that defines the upper-left of the rectangle-of-interest for the src Surface.</param>
/// <param name="roiSize">The size of the rectangles-of-interest for all Surfaces.</param>
