VirtualDub (x64 bit) full changelog

Filters: Added compatibility option for filters that rely on constant buffer addresses.

Filters: Added compatibility option for filters that rely on constant buffer addresses.

* Fixed occasional hang with certain conversion paths from 8-bit (256
color) to YCbCr formats.
* Fixed bug where two curve points on top of each other in the curve editor
didn't save properly in script files.
* Fixed decompression error in IFF ANIM decoder when entire bitplanes were
skipped.
* Filters: Fixed glitches in IVTC pattern in the first five frames of
video.
* Filters: Fixed occasional crash when 3D acceleration is enabled and the
3D device is lost.
* Filters: Fixed bugs where the curve display would either show the wrong
frames or fail to step in certain circumstances.
* Filters: Blends are no longer allowed on filters where the input and
output have different formats; this didn't work and produced a corrupted
image.
* Filters: Fixed crash in smoother filter with MMX disabled.
* Decoders: Fixed crash in Motion JPEG decoder on certain kinds of corrupt
data.

Bugs fixed:
· AVI: Modified indexing traversal to handle deeply nested hierarchical indices.
· Filters: Rescaling after changes to filter chain now extends or trims ending ranges as needed to match changes to frame count.
· Filters: Fixed bug where a filter capable of both 3D accelerated and unaccelerated modes (resize) could force a conversion to YV24 at its input when RGB32 was a better match.
· Filters: Filter preview no longer always runs the filter chain with the input video mode set to default.
· Display: Added workaround for video card/driver combos that perform extremely poorly with DirectDraw/Direct3D blits overlapping a secondary monitor. This can be toggled in Options > Preferences > Display.
· Command line: The warning dialog at the end of command line processing is now suppressed if /x is specified.

regressions fixed:
· Filters: Fixed filter errors not showing up properly.
· Filters: Fixed crash when PNG decoding error occurs with logo filter.
