SPX 迭代需求

[nighca]

Go+ Builder v1.3

1. ~~简化 Sound 的引入与播放，详见 https://github.com/goplus/builder/issues/443~~
2. ~~支持通过配置文件指定 window size（现在只支持通过配置文件指定 map size），详见 https://github.com/goplus/builder/issues/459~~ （spx 支持通过配置文件中的 run 字段指定 window size）
3. ~~修复 Backdrop 填充 mode 的问题，详见 #459~~
4. ~~修复浏览器中音频播放的问题，详见 https://github.com/goplus/builder/issues/445~~
5. ~~命名调整，stage costume / scene -> backdrop~~

注意：更新spx 后，根据当前Issue 第五条, 需要对项目中的 index.json 资源进行重命名 命名调整:

• scenes-> backdrops
• costumes->backdrops
• sceneIndex ->backdropIndex
• currentCostumeIndex ->backdropIndex

[nighca]

backdrop 相关命名调整应该还包括

spx.Game 方法名：

• SceneName -> BackdropName
• SceneIndex -> BackdropIndex
• StartScene -> SetBackdrop
• NextScene -> NextBackdrop
• PrevScene -> PrevBackdrop

spx.eventSink 方法名：

• OnScene -> OnBackdrop
