did some tests, but i have feeling it remove bmap in some cases and in some dont.

PANEL* panel = pan_create("bmap = test.bmp", 1);
this seems to remove bmap too - atleast i dont see used memory growing when removing this.

PANEL* panel = pan_create("bmap = NULL", 1);
panel.bmap = test;
In this case it seems dont remove it.

So i need to be vary in situation like this
PANEL* panel = pan_create("bmap = test.bmp", 1);
ptr_remove(panel.bmap);
Because it seems im removing all images who now used test.bmp.

I have feeling pan_create makes global bmaps. So in first case it deletes panel, but possibly left bmap undeleted.
