示例1: Cursor

/**
* Constructs a new Cursor, with the given parameters. Mouse must have been created before you can create
* Cursor objects. Cursor images are in ARGB format, but only one bit transparancy is guaranteed to be supported.
* So to maximize portability, lwjgl applications should only create cursor images with 0x00 or 0xff as alpha values.
* The constructor will copy the images and delays, so there's no need to keep them around.
*
* @param width cursor image width
* @param height cursor image height
* @param xHotspot the x coordinate of the cursor hotspot
* @param yHotspot the y coordinate of the cursor hotspot
* @param numImages number of cursor images specified. Must be 1 if animations are not supported.
* @param images A buffer containing the images. The origin is at the lower left corner, like OpenGL.
* @param delays An int buffer of animation frame delays, if numImages is greater than 1, else null
* @throws LWJGLException if the cursor could not be created for any reason
