Apparently the default value of the wantsBestResolutionOpenGLSurface
property changed with macOS Catalina 10.15
|

Another way to support what occurs under macOS 10.15 where the bitmap graphics context
prepared by the system when drawRect: runs sometimes changes its number of bytes/row
even if the width and height are unchanged.
This is expected to perform better when the number of bytes/row alternates between
two values.

Under Catalina, the bitmap graphics context prepared by the system when drawRect: runs
sometimes changes its number of bytes/row even if the width and height are unchanged.

Calls to CGBitmapContextCreateImage() and CGContextDrawImage() are replaced
by faster calls to memcpy().

run-time
The code to determine whether the GTK library is available is now in Fl_X11_System_Driver::probe_for_GTK()
called both by Fl_Printer::begin_job() and Fl_Native_File_Chooser.
New Fl::option OPTION_PRINTER_USES_GTK allows to deactivate use of
the Gnome print dialog.
Minor change in Fl_Native_File_Chooser: GTK version 3 is searched before version 2,
whereas the search order was the opposite before.

Subject "Bug in 1.4 Displaying PNG under x64 Kernel x86 app." in fltk.general
contains a report by Darren Legge that presents the problem,
and a later post stating the code modification does fix the problem.

src/Fl_File_Icon2.cxx

The only known warnings are now in src/Fl_x.cxx as mentioned in
comment #1.

With reference to Sanch's patch from the STR, plus some extra mods
for handling edge conditions (such as root()) and comment clarifications.

The case was under macOS with a non-GL parent window mapped to a retina display
containing a GL subwindow and if the app did not call Fl::use_high_res_GL(1).

This new implementation does all screen drawing through the drawRect: method.
The benefit is that [[NSGraphicsContext currentContext] CGContext] provides
a system-built drawing context whose product ultimately appears on screen.
Feed-back from the fldigi FLTK application shows that this procedure is
measurably faster that the previous one when drawing a rapidly changing image.

Users can press ctrl-c (or ctrl-x) while using the fl_color_chooser()
function or the Fl_Color_Chooser widget to copy the current color
selection to the clipboard.

X11 requires to process differently paste if both copy and paste are within the
same app or are in 2 separate apps. This was implemented for paste of text.
It's now also implemented for paste of image.
|

When copying graphical data to the clipboard with Fl_Copy_Surface,
both a vectorial and a bitmap versions of the graphics are copied.

This is relatively to Catalina public beta for now.

This bug could cause memory allocation/free errors and eventually
cause a crash.

window.
The bug is that the app freezes for a few seconds before the yellow transient window is closed
if the close message is set from within a timer callback.
If the window to close returns NO to the canBecomeKeyWindow message, the bug does not occur.
Anyway it's good that canBecomeKeyWindow returns NO for a window with the OUTPUT flag.

Drawing the window titlebar to a PDF context does not work with Catalina Beta.

This method can be called after all menu modifications to make sure
the menu() array is relocated (copied from the internal working area)
to a private place owned by the Fl_Menu_ instance.
menu_end() is now called in Fl_Menu_Button::popup() to make sure
the menu array is in private storage.
This fixes STR 3523 w/o user code changes. Calling menu_end() is
in most cases optional.
Todo: call menu_end() where useful (or necessary), e.g. in
Fl_Choice, Fl_Menu_Bar, etc. ?

Try to make `make depend' independent of locale.

As discussed in fltk.general, valgrind reported errors when gl_draw()
is called and the text is converted to a texture (i.e. when testing
whether the texture already exists).
We need a length check to make sure we don't overrun text buffers.
See threads "gl_draw" and "gl_draw - [General Use]", respectively,
started on Jun 19, 2019.

Per-Monitor V2 awareness mode is supported on Windows 10 1703 or above
and has window title bars correctly scaled on HighDPI screens.
Before this commit, FLTK Windows apps were "Per-Monitor-V1 DPI Aware".
FLTK apps detect at run-time whether the V2 mode is possible.

titlebar is partially out of screen
|

The new argument gives the window to be captured, or NULL to indicate capture
from the current offscreen.
Calling this function becomes easier because less dependent on global variables.

Fl::set_font(Fl_Font, const char*)

Previously, each time fl_font(fnum, fsize) was called, functions
pango_font_description_free() and pango_font_description_from_string()
would be called.
Now, pango_font_description_from_string() is called only once, the first time
an Fl_Font is used.
