Filters the image using a Gaussian filter kernel.
Use FilterGaussAdvanced if you want to supply your own filter coefficients.
Note that all FilterGauss functions currently support mask sizes up to 15x15. Filter kernels for these functions are calculated using a sigma value of 0.4F + (mask width / 2) * 0.6F.
