Clear Buffer

The following are two very simple OpenCL kernels , intended to be used as beginner's tutorial / study examples.

They show a simple way of clearing and updating the image buffer.

They both are setup to take an image input, one simply clears the image buffer to a constant colour, variables for which can be changed in the code.

The other takes the same image input , reads that image prior to applying whatever argument one has given to be done prior to updating the buffer.

In this case the argument is set to brightness.
