Is there an existing mechanism to do this, or do we need to interface to C code

If done right, the code doing coordinate conversion should be in library

That's how I would have implemented in it fpGUI as well. The higher
level code uses x, y as normal. The drawing backend code does
conversions
Hi,
Do I create a memory leak if I cast a PChar it a AnsiString. Then
append text to the AnsiString and then cast it back to the original
PChar?
eg:
var
Text: Pchar;<-- global var containing text.
procedure AppendText(const AText: string);
var
s: string;
begin
s := Text + AText;

The reason why I'm not sure, is because I created a simple console
test application. Initially, running the program, I got the correct
output. Then I thought I would enable 'heaptrc' (-gh compiler
parameter) to make sure I am not leaking memory in the application.
Now with heaptrc enabled, I get so

Crap, I forgot to explain the output.
t: string;
Text: PChar
The last line is the result of Text after AppendText() was called.

You read my mind. I was going to ask if it's ok to cast a PString to a PChar.
Trying what you suggested, I get the following compiler error.
project1.lpr(20,11) Error: Incompatible types: got "PString" expected "PChar"

Thank you for all your detailed answers. I read information about
lazbuild, but I think using Lazarus is much more easier. Since I am
used to vim, it might cost me some time to get familiar with it.
Thanks again.

Ah, now it works plus no memory leaks.
