I have run into an unusual bug with drawing polygons on the latest version (6.037) of the Windows client. When drawing a polygon with only 2 points, its x and y positions are offset by 0.5 tiles. If you attempt to draw a polygon with the coordinates {20, 20, 25, 25} it will instead draw it at {20.5, 20.5, 25.5, 25.5} and also move the rightmost pixel up by 1 pixel. This doesn't seem to affect polygons with more than 2 points or images though. Here is the code I used to test with:

PHP Code:

//#CLIENTSIDE
function onMouseDown(){
 temp.imageX=mousex;
 temp.imageY=mousey;

//Block image
 with(findimg(200)){
  image="block.png";
  x=temp.imageX;
  y=temp.imageY;
  layer=0;
 }

//Green triangle 2-D polygon
 with(findimg(201)){
  polygon={
   temp.imageX,temp.imageY,
   temp.imageX+2,temp.imageY,
   temp.imageX+2,temp.imageY+2
  };
  layer=1;
  red=0;
  green=1;
  blue=0;
 }

//Red line 1-D polygon
 with(findimg(202)){
  polygon={
   temp.imageX,temp.imageY,
   temp.imageX+2,temp.imageY
  };
  layer=2;
  red=1;
  green=0;
  blue=0;
 }
} 


And here is an image of the results:


The red line should line up with the top edge of the green triangle and the block image, but instead it is shifted down and to the right, and the rightmost pixel is raised up.
