GLMixer Code

Improved Output Render Widget and Window mechanism (both for blitted and textured FBO). Code cosmetics; changed 'signals' 'slots' into Qt macros 'Q_SIGNALS' and 'Q_SLOTS'.

Features improvements; display of mark in and out in property tree (and computation of correct frame number in VideoFile class), capture frame buffer and display in a dialog to save or create a source.

Edited wiki page through web user interface.

Moved the FPS display code to ViewRenderWidget (no need to have fps computation for every glWidget). Fixed a bug in capture source.

eye candy ; nicer shadow in mixing view.

Fixed BRIGHTNESS and CONTRAST generic implementation (and fixed error in Capture source formerly commited).

Implementation of CAPTURE SOURCE class; this was necessary to allow for the dynamic update of its content when applying filters. On the way, little programming issues were fixed.

Fix incorect mask blending (now based on black masks). Some minor bug fixes (prevent negative depth).

Implemented MASK with correct blending and property selection. Improved property browser a bit, and added an auto warning FPS display in case FPS drops dangerously.

Implemented blending MASKS and filtering. Small modifications of source update mechanism to allow for an update request.
