On some GPUs/drivers (seemingly nvidia) and screen sizes, VSE
vectorscope and sometimes waveform have "garbage" artifacts around
them.

Root cause unknown (driver bug?), for now similar fix as a while ago
in #112665: explicitly draw opaque background (with alpha=1), and then
use alpha blending for the scopes texture display on top of that.

Checking now, but would prefer if @Jeroen-Bakker was the primary reviewer here...

Yeah, this driver bug is haunting Blender for the last 6 months at least. So pre-drawing a quad is a fine solution for now.
