Implemented features

• optimized rendering without local framebuffer, in STM32 case 1 to 32 lines > buffer can be used
• pattern based background
• 3D starfield
• no floating point arithmetic
• no slow trigonometric functions
• rotations around X and Y axes
• simple outside screen culling
• rasterizer working for all convex polygons
• backface culling
• visible faces sorting by Z axis
• Tested with stm32duino and Arduino IDE 1.6.5
