[Win32k]
- Plugged in region attribute support and added the PEB cache for it as well.
[Gdi32]
- Using CreateRectRgn only with attribute and PEB cache support.
[Testing]
- Wine tests: gdi32; clipping and dc. gdiplus; region. user32; dce. Same results.
- Applications, AbiWord 2.6.8, FF 3.5, miranda 0.7.19 unicode, putty, SeaMonkey 2.0,

- Since Brush/Pen and Region objects are sharable,,, we can just use

- // Kernel Space to User Space Pointer
- (PGDI_TABLE_ENTRY)->UserData = pBrushAttr;

- Notes:
- Testing with DC_ATTR works but has drawing difficulties.
- Base on observation, (Over looking the obvious) we need to supply heap delta
- to user space gdi. Now, with testing, looks all normal.
