DOSBox-X release 0.82.13 (2018-12-24)

DOS模擬器 DOSBox-X 發布新版，更新如下 :

0.82.13

• Mac OS X SDL2 builds now use the native OS X menu
  system instead of the "SDL drawn" menus.
• Mac OS X SDL1 builds now default to the OpenGL
  output (if compiled with OpenGL support). Under
  recent versions of OS X, OpenGL output gives
  better performance than surface (CGBitmap) based
  display.
• SDL2 builds now have working XBRZ scaler support.
• Mac OS X SDL2 builds updated to completely ignore
  touch events, because SDL2 sees the touchpad on
  Macbooks as a touchscreen. Prior to this fix, the
  DOSBox-X UI was unusable due to mixed input events
  from both the touchpad and the mouse input from the
  touchpad.
• SDL1 High DPI support for Mac OS X users with Retina
  displays.
• SDL1 fix for display problems (blank windows) on Mac
  OS X 10.14.x (Mojave).
• Windows builds (compiled with VS2017) now have working
  MT32 (Munt) emulation.
• Adjusting CPU cycles with F12 + - / F12 + + (Increment
  and Decrement Cycles shortcuts) now updates cpu cycles
  property. This fixes a problem where adjusting the cycle
  count then changing the CPU core caused DOSBox-X to reset
  the cycle count back to the original value.
• Linux/X11 support fixed not to assume XRandR extensions
  are present, but to instead ask the X11 server first.
• Simple scaler rendering has altered the RENDER start line
  state so that detection of a changed line triggers a block
  of rendering without compare within a limited count before
  checking again. This means a reduced CPU load with scalers
  because it only detects frame changes every line before
  changes detected, and then on average every 12th line
  when running the scaler code. Hopefully this helps the
  Raspberry Pi keep up with DOS gaming better.
• Simple scalers now offer compile-time (not run-time)
  option to omit per-pixel compare in scaler and process
  the entire scanline instead as a performance adjustment
  for slower and embedded systems.
• Video debug menu added. First item is one that blanks the
  display to test screen updating.
• Simple scalers (normal 2x-5x and SAI) revised to process
  changes and scaler rendering in larger blocks for possible
  performance improvement.
• Simple scalers fixed to properly compare all pixels to
  detect changes properly, instead of only the first 4-8
  pixels.
• EGA/VGA text rendering combined to reduce code copypasta
  and reduce bugs.
• VGA 16-color planar modes now obey CRTC byte/word/dword
  bits.
