解除更多的限制和一些新块的建议/Suggestions for lifting more restrictions and some new blocks

[vovahub]

很抱歉我有一个提议和想法，我在使用摄像机v2的时候发现我使用画笔扩展画笔只能在以xy为0为中心的舞台设定的长宽比内渲染，这或许和画笔本身这个扩展有关或者是Turbowarp本身，但总的来说或许是扩展问题。还有一点是“碰到边缘就反弹”的块我认为可以把他改成"碰到<角色菜单（包括舞台边缘）>就反弹"这或许更好（事实上是我扩展做不出来:P很抱歉但这或许对很多人比较重要）

I'm sorry, I have a suggestion and an idea. When using Camera V2, I found that when I use the Brush extension, the brush can only render within the stage's proportions centered at xy=0. This might be related to the Brush extension itself or to Turbowarp, but overall it seems to be an extension issue. Another point is the "bounce when touching edge" block. I think it could be changed to "bounce when touching <sprite menu (including stage edges)>", which might be better. (In fact, I can't implement this with my extension :P Sorry, but this might be important for many people)
