Support for themes on ownerdrawn menu

[malcompl]

Patch added support for themes on ownerdrawn menu.
The menu looks like a native, but to ensure full compliance apperance with the native menu still missing a few things:

• misalignment of accel text
• draw correct std check/bullet mark if item is check/radio and bitmap is not set

I will be work on this problems in next separate patches.

Thanks for the patch, before looking at it: do I understand correctly that it's for the "owerdraw" branch (and not for the trunk)?

[malcompl]

Yes, it's for the "ownerdraw-refactor" branch.

Correct small bug and added support for pseudo menu themes on Windows XP.

[vadz]

Applied with a couple of very minor changes, thanks (and sorry for the delay).

Looking forward to the next patches and to merging the ownerdraw-refactor branch into trunk!

Small patch for resolve the 2 problems:

- The text is one pixel too low in owner-drawn case.
- The check mark is one pixel too high.

(In [62721]) Fix off by 1 errors in owner-drawn menu drawing code in wxMSW.

The label was offset by 1 pixel vertically and the check marks were 1 pixel
too wide compared to the native ones under XP, correct this.

Closes #11420 (again).

[VZ]

(In [63223]) Use theme functions for drawing owner-drawn menus.

This makes the menu items with custom attributes or bitmaps look more native,
especially on post-XP systems.

Closes #11420.
