love.graphics (简体中文)
The primary responsibility for the love.graphics module is the drawing of lines, shapes, text, Images and other Drawable objects onto the screen. Its secondary responsibilities include loading external files (including Images and Fonts) into memory, creating specialized objects (such as ParticleSystems or Framebuffers) and managing screen geometry.
love.graphics模块的主要功能是绘制图像（文字、形状、线、图片Image、其他Drawable）到屏幕上。次要功能是将外部文件（图片Image、字体Font）加载到内存中。建立专门的对象进行管理（比如ParticleSystem、Framebuffer）。
LÖVE's coordinate system is rooted in the upper-left corner of the screen, which is at location (0, 0). The x axis is horizontal: larger values are further to the right. The y axis is vertical: larger values are further towards the bottom.
LÖVE的坐标系统如下图所示，以左上角为原点，横向延伸为X轴，纵向延伸为Y轴。
In many cases, you draw images or shapes in terms of their upper-left corner (See the picture above).
在许多情况下，你绘制的图片和图形都是以它们的左上角为起点。 （如上图）
Many of the functions are used to manipulate the graphics coordinate system, which is essentially the the way coordinates are mapped to the display. You can change the position, scale, and even rotation in this way.
我们提供许多函数来用于操作“图形坐标系统”，坐标系统是图像显示的本质。通过操作坐标，你可以改变位置、大小、甚至旋转。
