Primary change is to replace most control/window borders with
AUI pane borders. We implement our own AUI border drawing
routine which avoids the ugly one-pixel white frames around
dark canvasses.
Also increases the signal-to-noise ratio of all the pane
creation code in the various frames.
Improve dialog layout and fix UI policy issues with all of the dialog
boxes in the Gerbview and Pcbnew code paths.
Updated the use of component to footprint where appropriate.
eeschema now supports arbitrary colors for all object types, and
pcbnew does in GAL canvas. When switching from GAL to legacy canvas,
pcbnew will convert colors to the nearest legacy color.
They are now member of EDA_DRAW_FRAME.
This change could fix Bug #1330781 (Background color change in Eeschema affects background color in Pcbnew)
Show page limits has meaning only for the schematic editor, the board editor and the page layout editor.
Draw background color selection exists only in eeschema and page layout editor.
In pcbnew, only a black background is allowed.
A side effect is now the user should set the background color in schematic editor, and the library editor (2 different options).
The default is still the white color.
Page layout editor: Add bitmap items to the page layout existing items.
Now a bitmap image can be added to a page layout description. Currently the bitmap is expected having a 300 ppi definition.
Note: not all plotters can plot a bitmap, and in this case the bounding box is plotted instead of the bitmap
