What is the purpose of the pixels dictionary member in the Outline examples?

[kallistisoft]

I've looked everywhere in the documentation and can't find any description of the pixels dictionary member which is passed to the Application class in the piu/outline examples.

export default new ClockApplication({}, { pixels: 240 * 32 });

So... I have several questions about the Application dictionary object:

• What is the purpose of the pixels member?
• What is the default value for pixels?
• What is the default value for commandListLength?
• What is the default value for displayListLength?

In brief:

• The pixels property defines the number of pixels in the render buffer using by Poco. The default is 2 scan lines of pixels. More pixels improves rendering performance. Practically speaking, increasing it much beyond 32 scan lines generally doesn't make much difference however. The details depend on what your project draws, so some experimentation and watching the rendering frame rate is usually appropriate.
• The commandListLength is the space reserved (in bytes) for Piu drawing operations. These are high level commands. The default is 1024.
• The displayListLength is the space reserved (in bytes) for Poco display list operations. These are low level commands. One Piu drawing operation may result in several display list operations, so the display list is sometimes larger than the command list. The default is 1024.
