Detailed Description

A lowest-common-denominator implementation of LowLevelGraphicsContext that does all its rendering in memory.

User code is not supposed to create instances of this class directly - do all your rendering via the Graphics class instead.

const [virtual]

Returns true if this device is vector-based, e.g.

a printer.

Implements LowLevelGraphicsContext.
