2e9f9f4929 - char width switch feature (8 / 9 pixels) implemented in display library win32.
If the font height is smaller than 14, a Windows font with a fixed width of
  8 is used (minimum height 12).

3a788ddcf4 - char width switch feature (8 / 9 pixels) prepared for all display libraries
and implemented in SDL
  * sequencer controller register 0x01 bit 0 controls the width of the characters.
    This value is used to calculate the screen width.
  * attribute controller register 0x10 bit 2 controls the appearance of graphics
    characters (ASCII 0xC0 - 0cDF). A change of this value forces a charmap update
    to rebuild the font bitmaps.
  * the SDL display library uses the new feature described above
  * the other display libraries recalculate the screen width, since they are using
    a fixed font width of 8 for now.
- VGA: attribute controller register 0x10 bit 2 (enable_line_graphics) does not
  switch the palatte in CGA mode

a17d06abcb Optimized the main cpu loop iCache checks to remove a redundant
check.

Commented out a number of instances of invalidate_prefetch_q(),
for branches which do not change CS since the EIP window mechanism
takes care of validating that EIP lands in the current page or not
in the main cpu loop anyways.

Fixed a couple cases (v8086 mode and real mode) of loading CS where
the EIP page window was not invalidated in segment_ctrl_pro.cc.
That may fix some aliasing problems reported before (OS2).

46d5548439 - modify the horizontal pel panning value of the tm_info structure if a char
width of 9 is enabled. For now, a panning value of 8 must be decremented.

36959329c5 - more accurate emulation of the horizontal and vertical retrace
ATTENTION: the Elpin VGA BIOS uses a delay of 280 vertical retraces after
  displaying the copyright text
- changes to the horizontal or vertical pel panning registers force a redraw of
  the screen
- screen update problems in text mode fixed
- sort order of the CRT register write cases changed

091052e199 - reverting to previous revision (xfer8 1.15, xfer16 1.21, xfer32 1.21)
as it breaks AMD64 support.

  is active
- force a resize of the screen after a change of the display mode (text/graphics)
- mem_write(): skip the rotation of the cpu byte if 'data_rotate' is 0

f43d2fe3e9 - backport of the BRANCH_HARDDISK_MODES to the main branch.
You can now choose for each disk on the ata interfaces the
  disk mode, between :
    - flat : one file flat layout
    - concat : multiple files layout
    - external : developer's specific, through a C++ class
    - dll : developer's specific, through a DLL
    - sparse : stackable, commitable, rollbackable
    - vmware3 : vmware3 disk support
    - undoable : flat file with commitable redolog
    - growable : growing file
    - volatile : flat file with volatile redolog
    - z-undoable : gziped flat file with commitable redolog
    - z-volatile : gziped flat file with volatile redolog
  A new "bxcommit" utility can merge commitable redologs to
  flat images.

b3d16a48ef - apply another speedup patch from Conn Clark.
Notes from the author:
Here is another one of my speed up patches. Unlike my previous speedups
this one will help more platforms than just X86. It cleans up the Data
Xfer instructions. Since the Data Xfer instructions are the most often
executed instructions it gives a noticable boost in speed. The basic
optimization technique was to eliminate intermediate variables and pass
a pointer to the final destination or original source to the
read_virtual_whatever and the write_virtual_whatever functions.

b937905a97 - dotclock/2 switch implemented - stored in new variable 'x_dotclockdiv2'.

  VGA modes.

- removed trailing spaces in VBE update code

8850cbf768 - removed BX_CPP_AttrRegparmN() from the i/o read handler. The read access
failed with this optimization. I guess the reason for the failure is the
  void* argument.

3411535a8b - 'split screen' feature for standard VGA 16-color modes implemented
* new variables 'line_compare' and 'vertical_display_end' depend on CRT
    register values
  * implemented 'split screen' in functions update() and mem_write()
- mem_write(): CGA section: unnecessary variable 'isEven' removed

d02c729791 - removed variable 'scan_bits' and added new variable 'line_offset'. It specifies
the address offset between two lines on the screen in all VGA modes.
  It depends on the CRTC offset register value and the address mode (byte, word,
  dword)
- moved screen update code to the end of the write handler. If a register change
  should force a redraw of the screen, the variable 'needs_update' must be set
  to 1.
- changes to the attribute controller palette index register now force a redraw
  of the screen
- modeX: calculation of the tile numbers fixed

b1324da2e1 - function mem_read() rewritten
* check memory mapping before everything else
  * read mode 1 optimized using a part of patch.vga-mode2-speed-dohzono
- function mem_write(): check memory mapping before everything else
- writes to the CRT registers are handled only if the new value differs
- a CRT start address change forces a redraw of the screen

e79aa992af - emulated CGA graphics mode 160x100x16 colors implemented using the text mode
with 100 rows and a char height of 4
- raster operations AND, OR and XOR in write mode 2 implemented (part of patch #707931)
- use the vga_tile_updated array in modeX like other modes do
- small optimizations in the graphics update code
