Gundum Wing: Duo Maxwell:

No doubt and no matter how and otherwise:
Pictured buffer should be prepared in 2D Canvas in any way no matter how they prepared the double buffer or not.
Otherwise, you lost the control and flexibility for the flash and flushing memories.

1. When you draw the picture, ...
2. When you write the font as literature, ...
3. The flashing matter is not only for the 1.
4-1. In the 2, we can create the easy font animation and proof it.
4-2. We also can draw 3 lines as axex but it was flashing and we could not feel so as font in same process like 4-1.

*
In addition, we could write the font on the memorized buffer not attached from the basic process if we prepared the double buffer.
