Changes from 2.6.0 to 2.6.1 CVS

Additions

  • Added AsFloatf (plugin api) [todo: documentation]
  • TimeStretch: Updated SoundTouch 1.9.0 (Wilbert+IanB).
  • Conditional filters: Add offset parameter to conditional functions (Wilbert).

Bugfixes

  • SuperEQ: Gain arguments (the frequency bands) can only be int, enforce it.
  • Fix VDub plugin race on cleanup. (It was theoretically possible for the stub code to try to access the VDub plugin after it was released. The order of clearing things is adjusted to make it impossible and throw an error if it ever tried just to be sure.)
  • Fix handle leak with "Exists"(SEt).

Optimizations

Changes

  • Color conversion routines: Move matrix decision into constructor, overcome exceed cacheline.
  • Replace convert_a.asm for yuy2 to rgb by Softwire assembly.
  • Add __cdecl declaration to api calls (SEt).
  • Add VDCall as __cdecl to VDub api calls
  • Use LoadLibraryEx/LOAD_WITH_ALTERED_SEARCH_PATH instead of LoadLibrary for loading plugins.
  • Use GetVarDef instead of GetVar+ThrowError in several places.
  • Redo SEH exception handling code(IanB). VirtualQuery/GetModuleFileName + Trap on Invoke(SEt).
  • GeneralConvolution, Subtitle and ImageSource/Reader/Writer: Remove msvcP*.dll dependance.
  • ImageSource/Reader/Writer: added "msvcpXX.h" // Quick replacement for msvcp*.dll.
