GLMixer Code

Fixed bug in video seeking interaction on frameSlider.

Improved layout of Algorithm Source dialog

Made the catalog view visible only in mixing and geometry views

Integration of the sourcePreview widget (of class SourceDisplayWidget) in the control bar (and removal of the original attempt to put it into the MixingToolboxWidget).

Fix error recording high resolution with raw formats (high bitrate) by increasing buffer size.

Changed the Filtering category (controlled by 'disable filter' option) to be only related to the image processing filters. Color operations (brightness, hur, threshold, etc) are now always available, even in the simplified GLSL rendering code. This is apparently well supported by Jean's Mac (for which this option 'disable filter' was made)

Starting version 1.2.
Creation of MixingToolboxWidget (with all its new icons).

Fixed bug with alpha clear color (was zero !!!)

Fixed bug of capture source and save snapshot (ignore the QGLFrameBufferObject toImage() method which seems buggy) + associated changes in GUI dialogs.
