"Choose Footprint" does not use anti-aliasing settings specified

[Thomas Pointhuber]

The dialog "Choose Footprint" shows aliasing artefacts which are not present in pcbnew (Grid dots of different size).

The "Library Browser" does not seem to have such grid artefacts, but it does not use the settings specified for the pcbnew/footprint editor as well.

@Jeff,

does not seem to be fixed on my system. I still see the obvious differences in the grid. I think the viewer is using cairo while I'm using OpenGL in the footprint editor. Nevertheless, the cairo Anti-aliasing settings are not used in the viewer as well.

Hmm... that last commit was for a different bug. Must have fat-fingered the copy/paste.

In any case, this is because the canvas is hard-coded for the Footprint Viewer. We can probably do better now that we have Orson's EDA_DRAW_FRAME::LoadCanvasTypeSetting() stuff....

[Jeff Young (jeyjey)]

@Thomas, it attempts to read the anti-aliasing settings from PCBNew if it's running, otherwise from the config. Does it fail for you in both cases, or only one of them?

@Jeff,

seems to work fine in the windows which are using the settings.

But I have to note the settings do not affect all windows. Some of them always use the grid style and ignore user settings:

* Footprint Library Browser
* CvPcb
