Fix erroneous optimization in VECTOR2<T>::Rotate (which was made for angles in degrees): Angles are in radians, and only 0 rd rotation is skipped ( case very frequent, especially in eeschema)
* Add event handler to check all button clicks for default command event
IDs and handle them appropriately by either calling EndQuasiModal() or
passing the event up the event handler chain to allow the default dialog
handlers to perform their magic.
* Add event handler to handle the close window event properly.
* Add scope brackets so the wxBusyCursor will stop being displayed when
the footprint library loading is complete in CvPcb.
* Remove the artificial footprint library read error limit to prevent
potentially readable libraries from being loaded after the error limit
is reached.
* Change error message dialog to an HTML dialog so that potentially large
error messages can be displayed with scrolling and the ability to copy
and paste the error message for bug reporting purposes.
* Add busy cursor when loading the footprint libraries so the user has some
idea that something is happening while the footprint libraries are being
loaded.
(In this case the schematic frame exists, but some members are not initialized as expected, and a crash happens when calling the schematic editor dtor)
Minor other fix: avoid multiple very similar strings to translate in 3d_filename_resolver.cpp
* Refactor edit one field dialogs to use validators and transfer data to and
from window functions.
* Add code to DIALOG_SHIM to handle validation and transfer functions since
the base dialog class code is not called by EndQuasiModal().
* Add custom validator class for filtering field text control characters.
* Add new field validator to edit schematic component dialog field text
control.
* Add new field validator to edit fields in library editor dialog field
text control.
* Make a few LIB_PART member functions const.
The new (eeschema, so far) hotkeys editor uses the right-click menu for the
reset command, so the reset-to-default function that was added in 6652
(git:0cd7476) was not accessible from eeschema.
* remove duplicate code between draw functions and STROKE_FONT used in GAL. Use only STROKE_FONT methods in draw, plot and test DRC function for texts. It remove slightly different shapes between GAL and other calculations.
* fix incorrect bounding box for texts with overbar. Especially noticeable for texts with overbar inside a copper zone in Pcbnew.
* fix a few minor other bugs related to graphic texts.
