Detailed Description

template<ProcessingTarget target>
class Beatmup::AbstractBitmap::WriteLock< target >

Makes a bitmap writable for a specific target device.

Once instantiated on a bitmap, bitmap.getData() returns valid address. When destroyed, marks the bitmap being up-to-date in RAM and outdated in GPU memory. This lock may be used within tasks.
