DIB engine status

[Huw Davies]

Hi folks,

Here's an update on the DIB engine that I've been working on for the
last few months.  This work has been made possible by the generosity
of Google - so thanks go to them and of course to Dan.

You can find the code at http://repo.or.cz/w/wine/dibeng-hd.git

What's supported
================
- All dib section depths (including BI_BITFIELD support).

- Single pixel solid and dashed pens.

- The 16 rop2s.

- Solid and dib pattern brushes.

- A brunch of primitives for drawing onto all dib section surfaces.

- GDI32 apis: LineTo, Rectangle and PatBlt.

- An extensive test suite for all of the above.

What needs to be done
=====================
- Blitting (eg BitBlt, StretchBlt and StretchDIBits) - I have some
  hacks for these in my tree.

- ExtTextOut

- Many more GDI32 apis - a lot of these should be easy given that we
  have a set of underlying dib drawing primitives.

- Non-MM_TEXT mapping modes and world transforms.

- The initial interaction with GDI32 in BITMAP_SelectObject is hacky
  and needs some work.

- Lots more...



Note that at the moment it's essentially useless because of the lack
of blitting, so unless you fancy hacking on that yourself then you
probably don't want to bother fetching the tree.

I'm going to stop working on this for a while (lots of fun Outlook
2007 bugs for me to look at!), but will endeavour to keep the tree up
to date with respect to WineHQ.  If someone *does* want to hack on
this then feel free to send me patches!

Thanks,
Huw.
