DrawCache caches fonts that are created during a paint so they can be re-used. This is done to make painting more efficient on the assumption that most paint operations only use a small number of different fonts, but that each font is used repeatedly. The default is 5, which is generally more than enough, but if a control is using a lot of different variations of fonts, then it may improve performance to increase this number.
