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
- 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
- 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
- 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

- There is no need to recalculate size of the Icon, we already have this piece of information
- Draw monochrome cursor/icons, not only their mask.
svn path=/branches/reactos-yarotows/; revision=47495
- Simplify UserDrawIconEx
- NtUserCreateCursorIconHandle : Get Information from bitmaps even on indirect creation and fix calculation of icon height in case of monochrome icons.
Fixes ~15 user32:cursoricon winetests.

- Change ChangeDisplaySettingsExA to look more like wine's one
[WIN32K]
- Return correct value if buffer is to small in UserChangeDisplaySettings (wine tests)
- Do not set an invalid size to the devmode we're passing ti UserChangeDisplaySettings, we might access garbage
Now all ChangeDisplaySettings related wine tests pass.
svn path=/branches/reactos-yarotows/; revision=47386
- Set right flags when reading display modes from registry
- Implement UserEnumRegistryDisplaySettings
svn path=/branches/reactos-yarotows/; revision=47356
- Check devmode size in NtUserChangeDisplaySettings
- Copy memory instead of setting fields in UserEnumDisplaySettings, so we don't lost anything.
svn path=/branches/reactos-yarotows/; revision=47355
- UserChangeDisplaySettings : add some checks and fixes to what was passed to us
More wine tests pass.
svn path=/branches/reactos-yarotows/; revision=47354
- Set DISPLAY_DEVICE_PRIMARY_DEVICE to Graphics device object when creating the primary device object
- switch state flags of the graphics device objects when switching mode
- Only compare valid fields when searching for a device mode in a device object
- implement CDS_TEST flag in NtUserSetDisplaySettings
svn path=/branches/reactos-yarotows/; revision=47353
- Set NULL owner to copied bitmap when creating indirect icons
- Rewrite UserDrawIconEx, inspired from wine code
- fix palette creation for 16 bits DIB
- Always assign a palette to bitmap created with BITMAP_CopyBitmap and IntCreateCompatibeBitmap.
[USER32]
- Use DIB section when creating icons
- Use something called "header"
Now mode switching is almost glitchless.
svn path=/branches/reactos-yarotows/; revision=47140
- move IntEngMovePointer code into GreMovePointer
- Delete the mouse cursor before mode switch, to force setting a new one after a mode switch. Fixes cursor artifacts after mode change.
- Update TODO.txt
svn path=/branches/reactos-yarotows/; revision=46976
Don't call IntHideDesktop and co_IntShowDesktop for now. This doesn't seem to be neccessary and fixes a bunch of problems
svn path=/branches/reactos-yarotows/; revision=46953
- Do not create a PDEVOBJ for nothing at startup
- Create the surface for real in IntCreatePrimarySurface
svn path=/branches/reactos-yarotows/; revision=46930
- use a macro in RegReadDisplaySettings to make things smaller
- Send WM_DISPLAYCHANGE to all toplevel windows when changing mode
- leave UserChangeDisplaySettings when mode switching failed
svn path=/branches/reactos-yarotows/; revision=46701
- EngAcquireSemaphoreShared: update dwEngAcquireCount
- DC_LockDc/DC_UnlockDc: Acquire PDEV lock only for direct DCs, in that case also update the pSurface pointer
- When copying DC states, copy the surface only for memory dcs
- after switching the mode, update system metrics and redraw the desktop window.
- Remove testdraw code.
