Also makes y_scale a dynamic parameter for EFB copies, as it doesn't
make sense to keep it as part of the uid, otherwise we're generating
redundant shaders.
This stops the virtual method call from within the Renderer constructor.
The initialization here for GL had to be moved to VideoBackend, as the
Renderer constructor will not have been executed before the value is
required.
This removes OSD support for video software, but it was already broken before.
This commit does not try to fix coding style issues, the rewrite of this presentation API is splitted up.
Old code dumped the efb, which was no-longer relevant since the
backend gained xfb support.
New code dumps the colour texture which is about to be rendered to
the screen so correctly reflects the bypassXFB option.
This adds xfb support to the videosoftware backend, which increases it's
accuracy and more imporantly, enables the usage of many homebrew apps
which write directly to the xfb on the videosoftware backend.
