Some of these extensions included different pixel depth formats, alpha blending support in bitmap operations and brushes, anti-aliased primitive rendering and more complex primitive rendering.

这些扩展提供了诸如位图操作，画笔，抗锯齿和越来越复杂的Primitive渲染中不同像素深度格式，Alpha Blend的支持。

This algorithm avoids the numerous repeated operations for getting many pixel color values without increasing the number of push and pop operations.

改进后的算法不增加入栈出栈操作的次数，却免除了原算法中为获取众多象素颜色值所需要的大量重复操作。
