calculate a single pixel

Note: this method is called for complex

Parameters

result	is a float[4] array to store the result
x	the x-coordinate of the pixel to calculate in image space
y	the y-coordinate of the pixel to calculate in image space
inputBuffers	chunks that can be read by their ReadBufferOperation.
chunkData	chunk specific data a during execution time.
