Ian McInerney d44b04978a Allow enabling WXTRACE in release builds on all platforms
Setting the environment variable KICAD_ENABLE_WXTRACE now enables wx

Wayne Stambaugh 2b1bf369f2 Do not parent file or directory dialogs to panels.
Parenting dialogs to child windows of top level windows is most likely
not defined behavior.  It's also likely that this behavior varies across
platforms so it' best not to risk doing it.  wxWidgets does not check if
the dialog parent is actually a top level window.  There may be other
places we are doing this with our message dialogs so we should do an
audit.

jean-pierre charras a5ffcd0a55 void Prettify(): fix a bug in a corner case, when a string ends with '\'
A '\' in a string is encoded as \\.
A '"' in a string is encoded as \".
But prettify parser did not take in account a string encoded as "xx\\" (for xx\)
So we need to verify if a sequence is xx\" or xx\\", i.e. if there are a odd
count of backslashes before a '"'

Ian McInerney 9f66ddb27f Attempt to use IsAttached to identify if a menu is a menubar menu
We can't get a mouse position for a menubar menu's event, because the
mouse may be outside our canvas. The original hack to detect menubar
menus may not work fully, and there have been some crashes appearing on
macOS where menubar menus attempted to get mouse position information.

Instead of the hack, try using IsAttached() to detect if the menu is
attached to a menubar, and then gate mouse position access accordingly.

The new behavior is to only expand to the first child of the root sheet
level.  On very complex hierarchies, this makes the navigator far more
useful.

Do not update schematic hierarchy navigator on every edit.  Now only
sheet changes will trigger a rebuild of the tree.

These strings aren't actually used right now, but they may be used
in the future, so don't actually remove them but silence the error that
they aren't used.

Wayne Stambaugh eb3fd10af8 Fix obscured object selection issue in board and footprint editors.
This selection improvement feature is hidden behind the advanced
configuration key "PcbSelectionVisibilityRatio".  It is turned off (1.0)
by default.  Value values are from 0.0 to less that 1.0.  From testing,
using a value between 0.1 and 0.3 produces the best results.

This fix uses normal alpha blending described in the link below.  The
current design only uses the alpha of the object's color.  It could be
improved by doing a full color alpha blending but using the color alpha
alone seems to result in satisfactory results.
