Summary
Add an option to Monteverdi to force not using OpenGL Shading Language for rendering i.e. force to use the OpenGL 1 compatible mode (OpenGL texture).
The option consists in:
- a command line switch -1 (like OpenGL 1.x) or --no-glsl
- a View/Use OpenGL Shading Language menu item
Rationale
On some systems, required OpenGL 2.x and GLSL version are automatically found but rendering is not working correctly (seems to depend on driver implementation) [1]. Adding an option to force not using GLSL and use the OpenGL 1 compatible rendering of Ice would solve this issue.
Implementation details
Disabling the use of GLSL an initialization of Monteverdi is already implemented. So, the command-line switch would only require to add an option to the command line and pass the switch to the mvd::MainWindow.
Regarding the View menu item, a reset of the image-view and quicklook-view scenes requires improvement of the mvd::AbstractImageViewRenderer and mvd::ImageViewRenderer to force reset of Monteverdi and Ice scene and reload image data.
