An image loading and rendering library for sdl2 / sdl2-cairo

## Installation

This module can easily install via **Cabal**.

``` bash
> cabal update
> cabal install sdl2-cairo-image
```

## Usage

### Loading image

Assume one import this module as

``` haskell
import qualified SDL.Cairo.Image as I
```

One can load an image within an `IO a`.
For example,

``` haskell
main = do
   img <- I.loadRGBA8 PNG "wherever/your/image/is/img.png"
```

If this file is loaded correctly then `img` will be a `Image PixelRGBA8`.
If failed, `img` will be a default 5x5 image (i.e. `I.defImageRGBA8`).

### Displaying image
