通过 exSprite Component 的快捷选栏，列表中选择 TextureInfo/exBitmapFont, 快速切换None和Assets，之后确认选择，最终会导致crash. 在此过程中还会产生 null reference 的问题 #28

已在GetVertices中加入保护，由于未能重现，还需要你测试一下。

NullReference 的错误已经解决，但是 Crash 仍然存在。一个比较简单的重现方法是在 None 的下面的那个 TextureInfo上按 "箭头上"，这样他会在 None 和 TextureInfo之间快速反复切换。多试几次后，confirm，就会在反复试验中crash

Crash 的原因被锁定在 exEditorUtility.Init() 代码里。由于初始化了资源，并且初始化是在 Unity 推荐的 [InitializeOnLoad] 中进行。目前通过将 Init 中的代码挪到 Property 中来解决。

但是还是会出现另外一个叫做 PPtr cast failed when dereferencing! Casting from Texture2D to MonoBehaviour! 的报错信息。

发生的方法就是不断地点击 Camera 中的 Color 颜色，然后enter 确定颜色选择 我暂时认为这个是我们代码内照成的bug，虽然我网上找了下，有很多插件都有这种问题
