For your information. 

I just posted a new release of my 3D engine (OR version 4.02).
When you have time, give it a try, there is a demo that shall blow your socks off.

Now for your gauge, do you know the PlgBlt

Code:

PlgBlt

use:

• Works with a source HDC that has a bitmap selected; fills a dest parallelogram from a source rect.
  
• Great for rotation/scale/shear; pass the 3 destination points (TL, TR, BL).
  
• No per-pixel alpha; for alpha use
  
  Code:

  AlphaBlend
  (msimg32) or GDI+ / layered windows.
  
• Quality depends on the driver; try
  
  Code:

  SetStretchBltMode(hdcDest, HALFTONE)
  before calling.
  
• Optional 1-bpp mask lets you punch holes (simple transparency).
