The non-solid vline() is implemented by calling putpixel(), as I couldn't be 
bothered to duplicate all that drawing code, so unless the surface has 
already been acquired by the caller, it is probably locking and then 
releasing it once per pixel. If I'm right, this could be improved by 
acquiring it at the start of the vline() loop, and releasing after the last 
call to putpixel(), to avoid each putpixel() call having to do this manually.
