Pietro Cerutti 0bc079ccd5 - Update to 05_20131124 ... Changes: * The new library pic_util.s7i has been added. It contains utility functions for pictures. A picture is a simple way to describe graphic images as readable text. A picture is an array of strings, where every character describes the color of a pixel. * The programs castle.sd7, mahjong.sd7, pairs.sd7, panic.sd7, shisen.sd7, sokoban.sd7 and sudoku7.sd7 have been adjusted to use pic_util.s7i. * The pictures in pic16.s7i and pic32.s7i have been adjusted to be useable by pic_util.s7i. * The pictures cancel_pic, folder_pic and reset_pic have been added to pic16.s7i and pic32.s7i. * A function to convert a pixmap image to BMP format has been added to draw.s7i. * The function getPixelColor has been added to draw.s7i. * In the example programs all usages of the function clear without parameters have been replaced with clear(black). The function clear without parameters is deprecated. * Interpreter and compiler have been improved to support the actions DRW_GETIMAGE and DRW_GETIMAGEPIXEL. * The performance of the function strCLit in str_rtl.c has been improved by a factor of 10. * The function init_bstri_constants in s7c.sd7 has been improved to use the function c_literal instead of cCharLiteral. This way it cannot happen that a sequence like ??( is interpreted as trigraph sequence. As a side effect the performance has been improved also. * The function init_win_constants in s7c.sd7 has been improved to call getImage instead of getPixel. This improves the performance dramatically. * The functions prc_return and prc_return2 in prclib.c have been improved to avoid using block_body when it is NULL. * Spelling errors in chlog.txt, faq.htm, faq.txt, install.txt, manual.htm, manual.txt, problems.txt read_me.txt, src/read_me.txt, flistutl.c, flistutl.h, heaputl.c, heaputl.h and striutl.c have been fixed. * The function drwGetImage has been added to drw_x11.c and drw_win.c. * The function drwGetImagePixel has been added to drw_rtl.c. * The program chkccomp.c has been improved to write defines for NO_EMPTY_STRUCTS, HAS_SYMLINKS and HAS_FIFO_FILES to version.h.		2013-11-25 12:34:53 +00:00
