GROBW/GROBH vs GROBW_P/GROBH_P

[cyrille de brébisson]

Hello,

To add-lib to what Tim said, Cartesian coordinates are linked with the function grapher.
The function grapher does "lie" somewhat to the user in the xmin/xmax in order to try to generate simpler per pixel coordinates and to "hide" the menu...

The programming graphic drawing functions both have 2 versions. Per pixel and cartesian.

The "idea"/"design" behind the 2 was that, programmers would use the per pixel version for pretty much everything (as it is a 1 to 1 map).

There is one exception of course, it is if you want to draw things that will interract/intermesh with drawing coming from the function grapher. In this case, you should be using cartesian coordinates in order to make sure that the mappings are the same.
