load bitmaps on a thread to store them in a list

Hi,

I have been trying out your lib. Very nice!

I have built my own thumbnail viewer in .net. It is very fast due to blitting but I am thinking to use your lib as the backend instead. But I had a question. Can I blit/copy/move and area of the screen to another part of the screen so I only have render the new part?

All the best

The issue names no files, tests, or entry points. First clarify whether the request is for a Direct2D screen-region copy operation or threaded bitmap loading, then inspect the library's rendering and bitmap APIs; done requires a decided scope and an explicit, testable behavior.
