[poppler] [PATCH 0/4] Optimize SplashXPath/SplashXPathScanner

[Stefan Brüns]

The first 3 patches do some preparative cleanup/optimization.

The 4th patch contains the major optimization, replacing the
single intersections array with a better fitting structure.

Stefan Brüns (4):
  Splash: Reserve space for path segments upfront
  SplashXPathScanner: Reset span state explicitly when advancing line
  SplashXPathScanner: Clamp y range to yMin/yMax outside the loop
  SplashXPathScanner: Reduce complexity of sorting spans
