Themes
======
EmulationStation allows each system to have its own "theme." A theme is a collection of resources defined in an XML document.
Themes are loaded like this:
1. Initialize to default values.
2. If `$HOME/.emulationstation/es_theme_default.xml` exists, load it.
3. If there is a `theme.xml` present in the root of a system's `path` directory, load it.
IF NOT, If `$HOME/.emulationstation/%SYSTEMNAME%/theme.xml` exists, load it.
Example
=======
```
<theme>
<listPrimaryColor>0000FF</listPrimaryColor>
<listSecondaryColor>00FF00</listSecondaryColor>
<listFont>
<path>./../all_themes/font.ttf</path>
<size>0.045</size>
</listFont>
<descriptionFont>
<path>./../all_themes/font.ttf</path>
<size>0.035</size>
</descriptionFont>
<backgroundImage>
<path>./theme/background.png</path>
<tile>true</tile>
</backgroundImage>
<headerImage>
<path>./theme/logo.png</path>
<tile>false</tile>
</headerImage>
<scrollSound>./../all_themes/scrollSound.wav</scrollSound>
</theme>
```
Themes must be enclosed in a `<theme>` tag.
All paths automatically expand `./` to the folder containing the theme.xml.
All paths automatically expand `~/` to the home directory ($HOME on Linux, %HOMEPATH% on Windows).
Stuff you can define
====================

`<resourceName>./some/path/here.wav</resourceName>`
Only .wav files are supported.
`<scrollSound>` - No default. Played when a list scrolls.
`<gameSelectSound>` - No default. Played when a game is launched.

Nine Patches
============
EmulationStation borrows the concept of "nine patches" from Android (or "9-Slices"). Currently the implementation is very simple and hard-coded to only use 48x48px images (16x16px for each "patch"). Check the `data/resources` directory for some examples (button.png, frame.png).
