GLMixer Code

Edited wiki page through web user interface.

Important commit; implemented session SAVE and LOAD. This required to change some interface to the source class and to some child classes (opencv, media), to fix bugs in the reset of the views, etc. On the way of uniformization of the source API, i implemented the source 'color maps' to enhance the invert color single option.

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.

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).
