applying gb of 0.0 panics

[berkes]

When running the api and setting the Gaussian Blur attribute to 0.0, the upstream image handler library panics.

Hi @berkes

Thanks for reporting this. I initiated this project around 2 years ago and have not checked it ever since. It is most likely there is no boundary check on these input types. I marked this issue as a bug and will look into it sooner.

Thanks again

No prob. I just noticed this and thought you might at least want to know.

I was looking into rendering the text wit subpixelhinting or anti-aliasing of some sort. And to run that, I needed to "disable" the gaussian-blur. Which, I assume, was implemented as a quick hack for the lack of font-rasterization. Which seems impossible without using the imageproc crate.
