/*
* This file contains macros to aid in defining native graphics
* primitive functions.
*
* A number of useful building block macros are defined, but the
* vast majority of primitives are defined completely by a single
* macro expansion which uses macro names in the argument list to
* choose not only from a small number of strategies but also to
* choose macro packages specific to the source and destination
* pixel formats - greatly simplifying all aspects of creating
* a new loop.
*
* See the following macros which define entire functions with
* just one or two surface names and sometimes a strategy name:
* DEFINE_ISOCOPY_BLIT(ANYTYPE)
* DEFINE_ISOXOR_BLIT(ANYTYPE)
* DEFINE_CONVERT_BLIT(SRC, DST, CONV_METHOD)
* DEFINE_CONVERT_BLIT_LUT(SRC, DST, LUT_STRATEGY)
* DEFINE_XPAR_CONVERT_BLIT_LUT(SRC, DST, LUT_STRATEGY)
* DEFINE_XPAR_BLITBG_LUT(SRC, DST, LUT_STRATEGY)
* DEFINE_SOLID_FILLRECT(DST)
* DEFINE_SOLID_FILLSPANS(DST)
* DEFINE_SOLID_DRAWLINE(DST)
*
* Many of these loop macros take the name of a SurfaceType as
* an argument and use the ANSI CPP token concatenation operator
* "##" to reference macro and type definitions that are specific
* to that type of surface.
*
* A description of the various surface specific macro utilities
* that are used by these loop macros appears at the end of the
* file. The definitions of these surface-specific macros will
* usually appear in a header file named after the SurfaceType
* name (i.e. IntArgb.h, ByteGray.h, etc.).

* "LUT_STRATEGY" macro sets.

* There are 2 major strategies for dealing with luts and 3

*
* The 2 strategies are "PreProcessLut" and "ConvertOnTheFly".
*
* For the "PreProcessLut" strategy, the raw ARGB lut supplied
* by the SD_LOCK_LUT flag is converted at the beginning into a
* form that is more suited for storing into the destination
* pixel format. The inner loop consists of a series of table
* lookups with very little conversion from that intermediate
* pixel format.
*
* For the "ConvertOnTheFly" strategy, the raw ARGB values are
* converted on a pixel by pixel basis in the inner loop itself.
* This strategy is most useful for formats which tend to use
* the ARGB color format as their pixel format also.
*
* Each of these strategies has 3 implementations which are needed
* for the special cases:
* - straight conversion (invoked from DEFINE_CONVERT_BLIT_LUT)
* - straight conversion with transparency handling (invoked from
* DEFINE_XPAR_CONVERT_BLIT_LUT)
* - straight conversion with a bgcolor for the transparent pixels
* (invoked from DEFINE_XPAR_BLITBG_LUT)

/*
* The macros defined above use the following macro definitions supplied
* for the various surface types to manipulate pixels and pixel data.
* The surface-specific macros are typically supplied by header files
* named after the SurfaceType name (i.e. IntArgb.h, ByteGray.h, etc.).
*
* In the macro names in the following definitions, the string <stype>
* is used as a place holder for the SurfaceType name (i.e. IntArgb).
* The macros above access these type specific macros using the ANSI
* CPP token concatenation operator "##".
*
* <stype>DataType A typedef for the type of the pointer
* that is used to access the raster data
* for the given surface type.
* <stype>PixelStride Pixel stride for the surface type.
*
* Declare<stype>LoadVars Declare the variables needed to control
* loading color information from an stype
* raster (i.e. lookup tables).
* Init<stype>LoadVars Init the lookup table variables.
* Declare<stype>StoreVars Declare the storage variables needed to
* control storing pixel data based on the
* pixel coordinate (i.e. dithering variables).
* Init<stype>StoreVarsY Init the dither variables for starting Y.
* Next<stype>StoreVarsY Increment the dither variables for next Y.
* Init<stype>StoreVarsX Init the dither variables for starting X.
* Next<stype>StoreVarsX Increment the dither variables for next X.
*
* Load<stype>To1IntRgb Load a pixel and form an INT_RGB integer.
* Store<stype>From1IntRgb Store a pixel from an INT_RGB integer.
* Load<stype>To1IntArgb Load a pixel and form an INT_ARGB integer.
* Store<stype>From1IntArgb Store a pixel from an INT_ARGB integer.
* Load<stype>To3ByteRgb Load a pixel into R, G, and B components.
* Store<stype>From3ByteRgb Store a pixel from R, G, and B components.
* Load<stype>To4ByteArgb Load a pixel into A, R, G, and B components.
* Store<stype>From4ByteArgb Store a pixel from A, R, G, and B components.
* Load<stype>To1ByteGray Load a pixel and form a BYTE_GRAY byte.
* Store<stype>From1ByteGray Store a pixel from a BYTE_GRAY byte.
*
* <stype>PixelType Typedef for a "single quantity pixel" (SQP)
* that can hold the data for one stype pixel.
* <stype>XparLutEntry An SQP that can be used to represent a
* transparent pixel for stype.
* Store<stype>NonXparFromArgb Store an SQP from an INT_ARGB integer in
* such a way that it would not be confused
* with the XparLutEntry value for stype.
* <stype>IsXparLutEntry Test an SQP for the XparLutEntry value.
* Store<stype>Pixel Store the pixel data from an SQP.
* <stype>PixelFromArgb Converts an INT_ARGB value into the specific
* pixel representation for the surface type.
*
* Declare<stype>PixelData Declare the pixel data variables (PDV) needed
* to hold the elements of pixel data ready to
* store into an stype raster (may be empty for
* stypes whose SQP format is their data format).
* Extract<stype>PixelData Extract an SQP value into the PDVs.
* Store<stype>PixelData Store the PDVs into an stype raster.
* XorCopy<stype>PixelData Xor the PDVs into an stype raster.
