further improved the dynamic receive send/change to avoid potential crash when changing the next memeber of the same bindlist

Fixed crash when trying to do dynamic change of receives on iemgui objects (affects also all objects that allow for dynamic changing of the bindlist)

added PDL2ORK define to distinguish between pdl2ork capabilities and vanilla pd and thus make externals work with both pd vanilla and pd-l2ork

Finished fixing inconsistency from the iemgui and non-gui fonts. This will break font appearance in older patches but looking forward will make things a lot more consistent. This is in part backported from the 0.43 branch.

*creating abstractions from menu does not dirty the canvas
*add minimum and currentvalue in addition to maximum of the signal magicglass
*first tests in improving consistency of fonts between vanilla and iemgui objects (in progress)

*fixed bug where objects were selected via a mouse click based on their left-to-right rather than top-to-bottom position
*fixed bug where undoing moving of a GOP object would incorrectly draw the object on top of other objects
*fixed bug where nlets would show on top of other objects when highlighted

fixed minor console resizing artifact where the bottom bar grew in size when y was greater than the original size

fixed wrong color fill for selected gop object when opening gop-ed subpatch, incorrect selection of all scalars inside gop-ed patch when it is being edited as a toplevel window, and a bug where repeatedly opening already open gop-ed patch does not re-focus its toplevel window

fixed noselect bug when line is selected and one clicks on a blank canvas which should also deselect selected line. also made pd_extrapath struct global as part of s_stuff.h so that ggee/image can use dynamic descriptors for retrieving of files (.e.g @pd_extra is translated to the pd's system-wide location of the extra/ folder)

fixed refocusing windows when closing sub-patch (or abstraction) where an invised parent would become visible instead of focusing on the next visible window.

hopefully finally array of improvements to the tooltip engine fixing offset bug when the window has scrollbars

further improved tooltip detection and reintroduced canvas tips that appear either in the bottom-left or top-left corners

code clean-up, more font resize/zoom fixes (hopefully done with it), and a minor bug fix for select all inside font window

settled on zoom (ctrl+mousewheel) which does the same thing as font resize simply because doing real zoom is extremely cumbersome with tcl/tk (esp. when one considers resizing images and also re-adjusting all coordinates inside c code to match newly zoomed state)
