Refactor: Public *Renderer / Unify Region Demos / Using own Screenshot (non AWT, plain GL2ES2)

Refactor: Public *Renderer
- Sharing common base abstract class Renderer.java
- Having public abstract classes RegionRenderer and TextRenderer
- Implementation non public, accessed via factory

- + shared code
- + clean API (same stuff)

Unify Region Demos

- reduced code / path, sharing common demo/test features Text/Region

Using own Screenshot (non AWT, plain GL2ES2)

- Remove AWT dependency
- Allow GL2ES2 screenshots
- Less complex
