Global:

• Changes CPU target support to SSE4.1 instead of SSE4.2
• Increase Max Target DgSurf Height from 4096 to 8192 (unlimited width)
• Changes Min Target DgSurf size to (w,h) (4,1)
• DgQuit increased compatiblity
• Add experimental DgWaitVSync (could reduce flickering, but not effectively reduce fps to screen refresh)

Graphics:

• Poly16: reject now single hline polygones; faster detection of (in, out or clipped); Optimization of some FILL funcs;
  Completely rewrite UV mapping, (left,write borders) hlines to be faster and more accurate (clipped/unclipped), this allowed multi-cores rendering without
  any visible change against single core; Reintroduce special case corners poly out detection, with vertical size reduction of clipped poly;
• RePoly16: Bug fixes, optimization/size reduction; stop handling 'N' Status (completely out) poly, instead REPOLY16 macro added, to avoid useless call;
• Line16,line16: size/speed optimization.
• Bar16, bar16: rewrite to use faster InBar16 instead of Poly16.
• PutXXXSurfXXX16: Performance/size optimization.
• DgSurfCPutPixel16: fix crash.

GUI:

• Bug fix unaligned 16bytes local DgSurf causing occasional crashes

Timer:

• Small rewrite in attempt to smoother/more precise synching.

Samples:

• Shadow: Add Multi-core resizing; Improve Multi-Core rendering up to 4 cores; Add parametric High quality rendering from 1.1 to 3.0 ratio;
  Add background panoramic sky background; Improve keyboard shortcuts; Enable double-buffer; optimize polygones sorting;
  Reduce unecessera big memory geometry allocation; Fix long standing camera concurrency between rendering/control threads, bug fixes, speed improvement;
  Add capability to show/hide info&help.
• Sprites: Add capability of switching/profiling any of the 6 possible Put functions (PUT, MASK PUT, COL BLND PUT, MASK COL BLND PUT, TRANSP PUT and MASK TRANSP PUT
• HelloWorld, Forest: Rework event handling and rendering loop and DWorker
