Cleanup TiledPage class.

The cleanup consists of:
1. renaming m_baseTextures to m_baseTiles
2. caching the inverse scale to speed up the draw calls
3. removing currentPictureMethod as it is available through GLWebViewState
4. adding comments to the public methods
5. some small source code optimizations
