[pygame] Re: BUG: dirty rect from draw.line too small.

[Rene Dudfield <renesd@xxxxxxxxx>]

I found out that the draw.line functions do not take the line width
into account when figuring out the size of the dirty rect.

You can work around it by growing the dirty rect by the size of the
line width.  However this will not give you an optimal dirty rect.


Here is some code for a work around from Magick on irc.

temprect= pygame.draw.line(screen,(255, 0, 0),firstpos,newpos,width)
temprect.inflate_ip(width*2, width*2)
