/*
 * 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)

/*
 * Antialiased glyph drawing results in artifacts around the character edges
 * when text is drawn ontop of translucent background color. The standard
 * blending equation for two colors:
 * destColor = srcColor * glyphAlpha + destColor * (1 - glyphAlpha)
 * works only when srcColor and destColor are opaque. For translucent srcColor
 * and destColor, the respective alpha components in each color will influence
 * the visibility of the color and the visibility of the color below it. Hence
 * the equation for blending is given as:
 * resA = srcAlpha + dstAlpha * (1 - srcAlpha)
 * resCol = (srcColor * srcAlpha + destColor * destAlpha * (1- srcAlpha))/resA
 * In addition, srcAlpha is multiplied with the glyphAlpha- that indicates the
 * grayscale mask value of the glyph being drawn. The combined result provides
 * smooth antialiased text on the buffer without any artifacts. Since the
 * logic is executed for every pixel in a glyph, the implementation is further
 * optimized to reduce computation and improve execution time.
