Proxy in Go to help web-developers to deal with images

Current version is a proof of concept. Proxy handles popular image formats and adds a label "<width>x<height>" at its top-left corner.

The result is like this:

Planned features:

• Parse a special image's URL parameter like "&xxx800x600" - expected dimentions. Check an actual image dimention and mark image correspondingly. Generate empty image in case GET fails

• web-admin UI, statistics, etc.

The project based on two great libaries: elazarl/goproxy and freetype-go. To install dependencies run:

go get github.com/elazarl/goproxy

go get golang.org/x/image/draw

go get code.google.com/p/freetype-go/freetype
