image before sending it to the mosaic.
- Add option ("chroma") to force the image chroma
- Remove alpha mask code
* mosaic.c: - Remove bluescreen code
- Misc cosmetics changes
* bluescreen.c: New bluescreen filter (mostly cut & paste from mosaic.c)
* alphamask.c: New alpha mask filter (mostly cut & paste from mosaic_bridge.c)
* invert.c: don't invert the alpha plane for YUVA images (We also need to
prevent that for RGBA images ... but that's not really used
currently)
* configure.ac, video_filter/Modules.am: add alphamask and bluescreen
if test "${SYS}" != "mingwce"; then
