Graphics32 is a rich, high-performance 32bits graphics library for Delphi, with extensive capability. This showcase was submitted by Christian-W Budde, who is an active contributor to the Graphics32 project.
Weak references and their zeroing is managed in Delphi NextGen through a global hash table, with a global lock, see Arnaud Bouchez take on it:

Also apart from the global locking which itself is bad enough, there are a couple further performance issues:
Very experimental support for LLVM in DWScript is now in the googlecode repository, thanks to the efforts of Christian-W Budde.
This is the beginning of the opening of new realms of possibilities for DWS!
LLVM support is currently centered around jit compilation, and at the moment doesn’t extend much beyond the needs of the Mandelbrot demo (see below for what is supported right now).
One of the “novelties” of the NextGen Delphi compiler is immutable strings, which I find quite puzzling, for lack of a better word, given that Delphi already had reference-counted copy-on-write strings, and the NextGen compiler uses reference-counted strings.
I always considered that Delphi’s String type was one of its remaining strong points, being a high-level abstraction (higher than Java’s or .Net’s String/StringBuilder dichotomy) with excellent low-level performance (on par with C/C++ character arrays).
From the recent discussions, it appears many don’t know what makes/made Delphi String so special, so here is a quick summary.
Here are the main DWS news items for May 2012

The second Smart Context 2013 has been announced! As with the previous round, first prize is a tablet device of your own choice (up to USD 750). This time the theme is “Game Development”
Visual Basic in its various incarnations and off-springs has super-powers when it comes to OLE Automation, aka late-bound COM through IDispatch.
Where do they come from?
This is a practical poll question, what would get you to buy a newer Delphi version?
What would you like to see most and foremost, and would most have a use for?
To force you to choose, you can only pick two items!
For a few weeks now, an experimental JIT compiler has been available in the DWScript SVN for 32bits code. A more detailed article into the hows and whats and WTFs will come later.
Consider this article as an extended teaser, and a sort of call for test cases, benchmarks and eyeballs on the source code.

Answering the call for showcases, Steffen Binas prepared a very nice set of screenshots for AquaSoft‘s Slide Show impressive product, which went far beyond the minimal requirement, so I’m posting a full-blown article about it. Following is the presentation of their software and how DWScript is used inside it.
When you need a powerful showcase I’d bet AquaSoft SlideShow is the one: http://www.aquasoft.de/diashow
Despite the simple name of the application it’s very powerful, just have look at the trailer video created completely with it.
