- Use newly introduced macros and get rid of related functions
- Ignore alpha channels of solid brush color
svn path=/branches/reactos-yarotows/; revision=48680
- 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
- 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.

- DIB data is not mandatory in CreateDIBitmap
[WIN32K]
- Simplify GreCreateDIBitmap
- Surface data should be 16 bits aligned
svn path=/branches/reactos-yarotows/; revision=47735
- Initialize the palettes before creating any bitmaps.
- Replace SURFACE_vSetDefaultPalette with an array of default palettes.
- Check iFormat in SURFACE_AllocSurface

Rewrite the bitmap API. There were a lot of bugs. NtGdiCreateBitmap allowed a negative height, leading to either topdown or bottomup bitmaps, a behaviour that Windows doesn't have. The function copied the bitmap bits directly from the caller to the bitmap using RtlCopyMemory, ignoring different scanline length and direction (resulting in bitmaps being upside down), not SEH protected. This function (IntSetBitmapBits) is replaced by a better solution UnsafeSetBitmapBits, that takes these things into account. The name is chosen to give a hint that the function can/should be SEH protected. IntSetBitmapBits is still there, as its retarded behaviour is actually required in some places. There were also IntCreateBitmap and IntGdiCreateBitmap, now both being replaced by GreCreateBitmap. The code that set the palette is removed, as it's already done in SURFACE_AllocSurface, here gpalRGB is replaced with gpalBGR, fixing some inverted color issues. The alignment correction in SURFACE_bSetBitmapBits is reapplied, now that the callers are behaving as they are supposed to do.

- Move RLE specific code to it's own file (rlecomp.c)
- Relace BitsPerFormat function with an array of UCHARs
- Rewrite surface creation. Surfaces are now allocated from one central function SURFACE_AllocSurface, which sets the size, iType, iUniq, the handle and the default palette.
- Implement SURFACE_vSetDefaultPalette, which sets the default RGB palette, based on bit depth.
- Implement SURFACE_bSetBitmapBits, wich sets cjBits, pvBits, pvScan0 and lDelta and allocates memory if neccessary.
- Use these functions for EngCreateBitmap, EngCreateDeviceBitmap, EngCreateDeviceSurface and IntCreateBitmap

Do not free the memory for the bitmap bits, when you have not allocated them. Fixes bugcheck with VBox driver.
svn path=/branches/reactos-yarotows/; revision=47609
- Allocate bitmaps as kernel sections, instead of from paged pool, like it's done in windows.
- Fix SURFACE_Cleanup. It was only freeing the memory for API_BITMAPs. If memory was allocated by a driver it never got freed.
- Add BMF_RLE_HACK flag to free decompressed RLE bits
- Support FL_ZERO_MEMORY in EngAllocSectionMem
- Set SURFOBJ::iType when creating a surface
svn path=/branches/reactos-yarotows/; revision=47606
- Simplify the logic of the mapping functions a bit, by using either FILEVIEW or ENGSECTION, not both.
- Set FILEVIEW::LastWriteTime
svn path=/branches/reactos-yarotows/; revision=47591
- 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
- When initializing the EXLATEOBJ to translate the solid brush color in EBRUSHOBJ_vSetSolidBrushColor, also pass the EBRUSHOBJs back color. This fixes wrong colors when the destination surface is mono (e.g. disabled buttons)
svn path=/branches/reactos-yarotows/; revision=47269
- IntGdiCreateBitmap : assign a default palette to the bitmap created
- Use IntCreateBitmap where we already have a bitmap to assign
- delete all mono bitmaps related hacks in xlateobj implementation, as now all bitmaps should have a palette
Fixes last immediately visible glitches when switching modes
svn path=/branches/reactos-yarotows/; revision=47203
- attach devinfo->hpalDefault to the pdevobj after enabling it
- attach this palette to surfaces attached to this pdevobj through EngModifySurface
- use this palette in several place
Partially fixes icon drawing after mode switch
svn path=/branches/reactos-yarotows/; revision=47137
- Use device string when given one in IntCreateDIC
[WIN32K]
- Exchange pdevmode when excahnging PDEVOBJ pointers
- Update Globals gdi devcaps when switching mode if ppdev is the primary surface
svn path=/branches/reactos-yarotows/; revision=47044
- 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
- Remove an ASSERT in DC_Cleanup
- Improve code in PDEVOBJ_vSwitchPdev (code shamelessly stolen from Jerome's earlier commit)
- Fix up GDIINFO in PDEVOBJ_bEnablePDEV instead of EngpCreatePDEV
- Update TODO.txt
svn path=/branches/reactos-yarotows/; revision=46975
- Update direct DCs surface before blit if needed
- call directly ppdev in MouseSafetyOnDraw{Start,End}
- use directly the PDEVOBJ surface in mouse operations
- Add some mouse-related sanity checks
