- Create the visible region upon DC initilization propely.
This is a leftover from 48579 and 48660.

- I watch and I learn : / has precedence over *=.
- Also make sure that we divide what we want to divide with the appropriate parentheses.
- Do not take care of alpha in other depths than 32 bpp.
svn path=/branches/reactos-yarotows/; revision=48488
Fix a bug when premultiplying the color values: The / operator has a higher precedence than *=, so "x *= byte / 0xff", is always 0 unless byte == 0xff.

- work directly with bitmap bits when alpha blending icons. This is permitted, those are API bitmaps.
- Do not create a stretched copy of source surface in EngAlphaBlend, handle stretching in DIB functions.
- Do so.
- Simplify DIB alpha blending for 24 and 32 bpp, implement generic alpha blend support for other depth.
svn path=/branches/reactos-yarotows/; revision=48483
- Did you know that we should ignore alpha channel of pattern in ROPs? You didn't, I didn't, now we do.
[WIN32K]
- Use BGR palette as default for 24 and 32 bpp bitmaps.
svn path=/branches/reactos-yarotows/; revision=48470
- Do not cast RGBQUAD to PALETTEENTRY or the other way around, you idiot.
- Report success even when we're asked fo 0 ScanLines in NtGdiGetDIBitsInternal.
svn path=/branches/reactos-yarotows/; revision=48417
- NtGdiGetBitmapBits : Bits we're given are 16 bits aligned.
- NtGdiGetDIBitsInternal : we must not stretch, for this there is NtGdiStretchDIBitsInternal. Use lower level functions to do the work, there is no need to create HDCs etc...
Now icons are back.

- Use correct offset in UserLoadImage, create the bitmap using display DC.
- BITMAP_GetObject : Report BI_BITFIELDS compression when we should.
- Use a 0 compatible DC when none is given in NtGdiCreateDIBitmapInternal.
This fixes some wine tests. Enjoy.
svn path=/branches/reactos-yarotows/; revision=48415
- Apply a better fix for correctly report 16 bits alignment for DDBs, and keep them 32 bits aligned as it should be.
- Reapply Pigglesworth patch, which was correct since mine was not.
Dedicated to tkreuzer, PigglesWorth and lassy, the three guys still on IRC to watch my commits at 3:30 AM.

- DDB are 16 bits aligned.
- Reset hdc field of the unselected bitmap.
- Lock it too, so it's not messed with when we unselect it.
- Move Pattern creation of IntGdiCreateDIBBrush to DIB_CreateDIBSection.
svn path=/branches/reactos-yarotows/; revision=48406
- Revert unwanted change and get back to PAL_BGR for default DIB palette mode.
Now yarotows looks like an OS again.
svn path=/branches/reactos-yarotows/; revision=48390
- Finally get rid of ProbeAndConvertToBitmapV5Info
- Rewrite renderBITMAPfromDIB, and a good bunch of DIB related functions accordingly.
- Rewrite BITMAP_CopyBitmap into something simpler.
- Use already existing DIB functions in IntGdiCreateDIBBrush
- Use DIB sections in NtGdiStretchDIBitsInternal and NtGdiSetDIBits.
- Use Bitmap hdc for NtGdiGetDIBitsInternal if there is one.
svn path=/branches/reactos-yarotows/; revision=48389
- Cast Colors to RGBQUAD in EngCreateBitmap, since that's what they are.
- Copy selected palette of the DC when creating a DIBSection with DIB_PAL_COLORS.
- Do not try to get Colors in NtGdiGetDIBitsInternal when bpp == 0, this doesn't make any sense.
- Get rid of SURFACE::dsBitfields and SURFACE::biClrUsed.
- Use RGB as default palette mod when creating the DIB Palette.
svn path=/branches/reactos-yarotows/; revision=48369
- rewrite UserLoadImage so that it uses information from the BITMAPFILEHEADER and probes the right buffer.
svn path=/branches/reactos-yarotows/; revision=48364
- Rewrite NtGdiGetDIBitsInternal, with WINE as a reference.
- Get back DIB Section creation to classic BITMAPINFO.
This si the beginnig of the end for all this BITMAPV5INFO stuff.
It is horrible, BITMAPCOREINFO->BITMAPINFO is already made in user mode, and V4 and V5 features are not used so often.
svn path=/branches/reactos-yarotows/; revision=48359
- More BITMAPINFO->BITMAPV5INFO
- Do not use PAL_BITFIELDS when creating the DIB palette and we know that it's RGB
- PSEH-ize NtGdiCreateDIBSection
svn path=/branches/reactos-yarotows/; revision=48248
- exchange mask and color bitmaps if needed in CreateIconIndirect
[WIN32K]
- Simplify a bit UserDrawIconEx
svn path=/branches/reactos-yarotows/; revision=48026
- DIB data is not mandatory in CreateDIBitmap
[WIN32K]
- Simplify GreCreateDIBitmap
- Surface data should be 16 bits aligned
svn path=/branches/reactos-yarotows/; revision=47735
- Split NtGdiCreateDIBitmapInternal with its Gre Counterpart
- Set bV5ImageSize if it was not already set
- Probe bits we're given in NtGdiSetDIBits
- SEHize clipboard image data access

- check for the type of the DC to restore to decide whether we should restore the surface
Fixes yarotows specific FF3 bug

- Improve readability in SetBMIColor
- Only when BitCount is <= 8, calculate the number of colors in the table
- Fixes a crash with VBox driver
svn path=/branches/reactos-yarotows/; revision=47724
If pbmiSrc->bmiHeader.bV5ClrUsed is 0, calculate the number of colors from the bit depth. Fixes black taskbar icons with vbox driver on 8 bpp
svn path=/branches/reactos-yarotows/; revision=47719
Small bug big effects: Use the correct offset when copying the BITMAPINFO, fixes taskbar icons regression.
svn path=/branches/reactos-yarotows/; revision=47709
- Initialize the palettes before creating any bitmaps.
- Replace SURFACE_vSetDefaultPalette with an array of default palettes.
- Check iFormat in SURFACE_AllocSurface
svn path=/branches/reactos-yarotows/; revision=47703
- More BITMAPV5INFO fun
- Probe max size we are asked for when converting to V5 Info
[USER32] [WIN32K]
- CreateDIBitmap : Move safety handling to win32k, where it belongs. More code cleanness!
svn path=/branches/reactos-yarotows/; revision=47701
NtGdiGetDIBitsInternal: don't use the unsafe usermode pointer after the BITMAPINFO has been converted and protect writing back the result with SEH.
