Main
- can be used as so/dll/dylib or statically compiled with your application
- rendering to own or any other prepared window
- logging
- resource loading from files, memory and zip archives
- multithreaded resource loading
- easy way to add supporting for new resource format

Configuration of
- antialiasing, screen resolution, refresh rate and vertical synchronization
- aspect correction
- title, position and size of window
- cursor visibility in window space

Textures
- supports tga, png, jpg and pvr
- correct work with NPOT textures
- control the filter parameters
- masking
- render targets for rendering into texture

Text
- textured Unicode-font
- rendering UTF-8 text
- rendering text with alignment and other options like size, color and count of symbols

2D-subsystem
- batch render for high-speed rendering
- rendering different primitives
- sprite engine
- rendering static and animated sprites and tiles
- rendering distortion grid
- rendering sprites with new texture coordinates(with the pixel dimension and the usual 0..1)
- control the blend mode and color mix mode
- control the color and alpha of vertices of sprites and primitives
- additional sprite transformations(flipping, zooming, vertices offset)
- fast clipping of invisible sprites
- 2D camera with ability to zoom and rotate the scene
