- Move from using include guards to pragma once. - Whilst this is non-standard and potentially makes the code less portable, it's supported by both gcc and msvc and should bringg increased compilation speed due to its optimized behaviour (doesn't need to invoke the preprocessor) - Patch by Amine Khaldi [amine.khaldi@reactos.org] svn path=/trunk/; revision=45685

[WIN32K] Rewrite of the GDI handle manager - The old handle manager used a completely retarded spinlock in combination with KeDelayExecutionThread() for both exclusive and shared locks. This is probably the most uneffective algorithm possible. It was also duplicating code everywhere and it was a overall mess It is now replaced with a lock-free reference counter for shared locks and a pushlock for exclusive locks. -> Better performance and scalability. - Allocate user mode object attributes from the new gdi pool. This way, we don't need any caching, since the pool serves as a cache. Its also much faster and uses much less memory. - Allow object allocations of different size, instead of fixed size from a table. This way a single allocation can take care of actual needs. - Allow allcoating objects without a handle and insert them into the handle table later - Properly synchronize the process GDIHandleCount. Now gdiview and taskmanager show the correct number of gdi handles. - Implement a new event tracking system, that is capable of tracking all reverences and locks of objects and pool allocations to help track possible leaks - Make sure that all objects of a process are deleted in cleanup - Make sure all usermode memory allocations are freed, when cleaning up the process pool. - Make sure that each object type is using the correct type of lock (either shared or exclusive, not a mixture) - Fix some object / reference leaks - Lots of inferface improvements - Use global variables for certain things instead of members in the mapped gdi handle table - Make IntSysCreateRectpRgn create a region without a handle - Fix detection od source and mask use in GreStretchBltMask - Use GDIOBJ_bLockMultipleObjects in NtGdiCombineRegion to avoid possible deadlocks - Fix NtGdiAbortPath to reset DCPATH_ACTIVE flag in the dc and only bail out on error, instead of always - Replace DC_AllocateDcAttr and DC_AllocDcAttr with DC_bAllocDcAttr using the new user mode pool - Remove DCU_SyncDcAttrtoUser and DCU_SynchDcAttrtoUser.

XLATEOBJ rewrite. The new XLATEOBJ is not allocated from paged pool anymore, but instead allocated on the stack and Initialized. Only when we habe more than a color table with more than 6 entries, we need to allocate an additional buffer. The new interface: EXLATEOBJ_vInitialize is the main init function. It takes a source and destination palette and back and fore colors for monochome surfaces. EXLATEOBJ_vInitXlateFromDCs takes the source and dest DC and is for color translation between 2 surfaces represented by 2 DCs. EXLATEOBJ_vInitBrushXlate initializes an XLATEOBJ for a pattern brush. Finally EXLATEOBJ_vCleanup needs to be called when the XLATEOBJ is not needed anymore. Implement individual iXlate functions for certain cases and store a function pointer in the EXLATEOBJ structure for quick access. Change the usage of the PALETTE.Mode member to be a flag instead of an enum, add usage of PAL_MONOCHOME, PAL_RGB16_555 and PAL_RGB16_565. Add gpalMono, which *should* be used as palette for 1bpp DDBs. Currently there's a hack in the XLATEOBJ init code, to hack around the fact that this is missing. Fix the Hatch brush patterns, as they were inverted. Implement PALETTE_ulGetNearestBitFieldsIndex and PALETTE_ulGetNearestIndex. Get rid of the XLATEOBJ for the mouse pointer instead realize the pointer before usage. Get rid of logicalToSystem PALETTE member. NtGdiGetDIBitsInternal: Don't create a DIBBrush from the BITMAPINFO, when pvBits is NULL, as the function might be uninitualized. This fixes a crash of gdi_regtest. The whole function is quite ugly and needs to be rewritten (like probably the rest of the DIB code). This fixes the problem of artifacts in the selected desktop icons and some color problems. svn path=/trunk/; revision=42391

Now the subsystem modules are located close to each other (like gdi32 and ntgdi, or user32 and ntuser). * Thanks go to the subsystem team for coming up with this nice layout, hopefully this will scale to the whole codebase layout soon. * Special thanks to Smiley for coming up with this cool idea :) svn path=/trunk/; revision=56311

[WIN32K] Implement CreateDIBPalette(), replacing BuildDIBPalette. It creates a palette without a handle and handles DIB_PAL_COLORS as well as DIB_RGB_COLORS. Additionally it now handles DIB_PAL_BRUSHHACK, which is used for DIB brushes, when DIB_PAL_COLORS is passed to CreateDIBPatternBrush(). The palette is not created directly, but instead the indices into the DC palette are put into the palette and the real palette is created, when the brush is realized. The latter is not yet handled. svn path=/trunk/; revision=56518
