Windows!

[luserdroog]

In a breathtaking hackathon, we've cooked up output devices for <del>X Windows</del> ahem.. The X Window System and Ms Windows!

 

Still pretty finicky. And doesn't select colors or draw properly. But 'loadgraphics' opens up a window. Now we're cookin'!

Latest version is doing some simple grayscale drawing on windows.

 

stuff like

 

 clippath fill showpage

 

 10 10 moveto

 100 100 lineto stroke

 

 10 10 moveto

 100 50 lineto

 0 setlinewidth stroke %uses the bresenham dda line algo

 stroke

 showpage

And the xcb version now has the same functionality as the windows device.

`erasepage` is really really slow.

We've now got greyscale drawing with both Windows and X.

 

To get the xcb stuff to compile, I had to manually install a number of

packages on Ubuntu:

 

 apt-get install libxcb1-dev

 apt-get install libxcb-image0-dev

 apt-get install libxcb-util0-dev

 

Some simple drawing tests have been added to the 'runtest' command.

Unfortunately, all three of my testing setups are currently crashing after

running the test twice.

 runtest

So, I've got some debugging to do.
