-; Change log :
-; 30 May 2003 : File creation
-
-; Section definition : We use a read only code section for the whole file
-.section __TEXT,__text,regular,pure_instructions

-
-; --------------------------------------------------------------------------------------
-; Single 32b pixel drawing macros
-; Usage :
-; DRAWMETHOD_XXXX_MACRO *pixelIN, *pixelOUT, COLOR, WR1, WR2, WR3, WR4
-; Only the work registers (WR) can be touched by the macros
-;
-; Available methods :
-; DRAWMETHOD_DFLT_MACRO : Default drawing method (Actually OVRW)
-; DRAWMETHOD_PLUS_MACRO : RVB Saturated per channel addition (SLOWEST)
-; DRAWMETHOD_HALF_MACRO : 50% Transparency color drawing
-; DRAWMETHOD_OVRW_MACRO : Direct COLOR drawing (FASTEST)
-; DRAWMETHOD_B_OR_MACRO : Bitwise OR
-; DRAWMETHOD_BAND_MACRO : Bitwise AND
-; DRAWMETHOD_BXOR_MACRO : Bitwise XOR
-; DRAWMETHOD_BNOT_MACRO : Bitwise NOT
-; --------------------------------------------------------------------------------------
