; TODO (4.1.0):
;   - optimize drawing (reduce flickering)
;   - syntax highlighting for different languages (plugins?)
;   - add vertical selection, undo, goto position, overwrite mode
;   - improve window drawing with small dimensions
;   - save settings to ini file, not to executable
;   - add prompt to save file before closing/opening
;   - other bug-fixes and speed/size optimizations
;
; HISTORY:
; 4.0.4 (mike.dld)
;   bug-fixes:
;     - statusbar contained hint after dialog operation cancelled
;     - small drawing fix for gutter and line saved/modified markers
;       (incorrect calculations)
;     - incorrect lines marking on Ctrl+V
;   changes:
;     - editor and other modifications to ease parts placement changing,
;       including changes in look
;     - modified/saved colors now match those in MSVS
;     - function 70 for *all* file operations (including diamond's fixes)
;     - use memory manager instead of statically allocated region
;     - case-insensitive filenames input, to be able to open/save files with
;       non-latin chars in name (russian etc.)
;     - reduced flickering (changes checker)
;     - overall code cleanup
;   new features:
;     - recode tables between CP866, CP1251 and KOI8-R (suggested by Victor)
;     - tabbed interface, ability to open several files in one app instance
;       (thanks IRC guys for ideas and testing)
;     - make any tab default to compile it disregarding currently active tab
;     - configuration dialog (colors, tabs positioning)
; 4.0.3 (mike.dld)
;   bug-fixes:
;     - 1-char selection if pressing <BS> out of real line length
;     - fault in `writepos`, added call to function 9
;     - main menu items weren't highlighted if popup opened and cursor
;       isn't in main menu item's area
;     - statusbar and textboxes drawing fixes (wrong colors)
;     - perform no redraw while pressing Shift, Ctrl, Alt keys
;     - data length from DOCPAK in string representation (fixed by diamond)
;     - compare file extension case-insensitively (fixed by diamond)
;   changes:
;     - function 70 instead of 58 for files loading/saving
;     - clientarea-relative drawing (less code)
;     - every line's dword is now splitted into 2 words;
;       low word - line block length, so max line length is 65535 now
;       high word - various flags. for now, only 2 of 16 bits are used:
;         if bit #0 is set, line was modified since file open
;         if bit #1 is set, line was saved after last modification
;       high word could also be further used for code collapsing and different
;         line marking features (breakpoints, errors, bookmarks, etc.)
;   new features:
;     - line markers for modified and saved lines
;     - status messages for various actions
; 4.0.2 (mike.dld)
;   bug-fixes:
;     - program terminates if started with parameters (fine for DOCPAK)
; 4.0.1 (mike.dld)
;   bug-fixes:
;     - unable to run program after exiting from main menu (Alt+X)
;   new features:
;     - integration with DOCPAK
; 4.0 (mike.dld)
;   bug-fixes:
;     - main menu popups' "on show" was called only for first shown popup
;     - clear selection on left/right arrow keys
;   new features:
;     - "replace" dialog (w/o "skip", "replace all")
;     - line numbers display
;     - options (except "appearance" and "smart tabulation")
;     - options saving (colors, window position, "Options" popup triggers)
; 4.0 beta 2 (mike.dld)
;   bug-fixes:
;     - unable to start if /rd/1/example.asm is missing (from Halyavin)
;     - clicking on menu items draws main window in popup (from Rohan)
;     - passed parameters aren't taken into account (from Mario79)
;     - background isn't erased if text lines < screen lines after
;       selection deletion (from Rohan)
; 4.0 beta 1 (mike.dld)
;   menu bar and popup menu;
;     removed buttons from the top and input fields from the bottom since
;     now they're accesible through main/popup menu;
;   improved keyboard handling (using 66th function);
;     support for almost all FASMW keyboard shourtcuts;
;   added text selection ability, standard selection operations
;     (copy,cut,paste);
;   new integrated dialogs (open, save, find)
;   fix to collapse SPACEs into TABs only for *.asm and *.inc files
; 3.78a (mike.dld)
;   fixed termination while typing in x positions higher than (line_length+10);
;   improved drawing on small heights
;     don't draw window while its height = 0 (Kolibri "minimize" support)
; 3.78 (mike.dld)
;   now lines may be of ANY length;
;     optimized memory usage (less memory for internal file representation)
;       after loading file, it's internal size equals to its real size
;       plus 14 bytes for each line (4 bytes for line length
;         and 10 spaced to the end - to reduce data relocations count);
;     completely rewritten keyboard handling;
;     added horizontal scrollbar;
;   all line feed formats are supported: WIN(CRLF),*NIX(LF),MAC(CR);
;   etc.
; 3.77 (mike.dld)
;   changed save_string to collapse SPACEs into TABs;
;   rewrote drawfile from scratch (speed++)
;     through some drawing improvements  needed
;     (some checkups to reduce flickering);
;   writepos (size--);
;   fixed drawing window while height < 100px, and for non-asm files;
;   several small fixes; speed/size optimizations
; 3.76 (mike.dld)
;   changed loadfile/loadhdfile to expand TABs into SPACEs;
;   changed TAB,ENTER,DELETE,BSPACE keys behaviour (rewritten from scratch);
;   vertical scrollbar;
;   extra window resizing capabilities (added a couple of constants);
;   completely new text cursor management & moving text cursor with mouse;
;   improved search function, moving cursor to beginning of text found;
;   adjustable max line width (change LINE_WIDTH & recompile) // (obsolet)
; 3.75a
;   fixed converting char to upper case in read_string
; 3.75
;   rewrote save_file from scratch; bugfix in loadfile;
; 3.74
;   optimisation
; 3.73
;   completly new load_file function
; 3.72
;   speed++
; 3.71
;   error beep
; 3.6,3.7:
;   many bugs fixed
;   simple toolbar
;   compile, run applications from TINYPAD, all fasm output is in debug board
;   TAB button
;   auto-indent
;   Ctrl+L - insert comment string
