When scanning a subdirectory on-demand ensure files aready present
are not added twice. Files or directory can be already present due
to dir monitoring create message.
Fix check for ignore files when adding a file to respond to a dir monitor
event to use each part of the file's path.
Fix C function to compare files for treeview placement.
Verity if dmon_watch returns an error.
Add a check if an added file for which we received a create event is
ignored based on the user's config.
Add some explanatory comments in the code.

Now we request a watch on the directory and we manage sending
and receiving directory change events.
The mechanism to update on the fly the directory scan is not complete.
The code to remove a file is there but we need to implement the code
to add a new file.
It is reported that the built-in lua function os.remove(path) does
not removes empty directories on windows. To fix this a system.rmdir
function is introduced that calls a native win32 function.
Also common.rm(path, recursively) was added which wraps system.rmdir()
to easily delete an entire folder with all its contents.
Add a renderer.font's method "copy" to clone the font object
by specifying an optional new size. In the size is not given
the size of the original object is used.
Should fulfill the request from issue #288.
Groups together consecutive mouse move events like done in core.step()
lua function but on the C side.
It does not introduce any meaningful speedup but it theory is more efficient and
simplifies the Lua code.
The simplification of the Lua code alone is enough to justify this change?
* Retrieve scale plugin from lite-plugins
* New implementation of scale plugin and font C API
Introduce two new C API functions, renderer.font.get_size and set_size
respectively to get the font size and to set the size to a new value.
Using these functions we don't need to know the name of the font but
we can just change their size.
Adapt the scale plugin to use the new C API function with minor adaptations
in the logic.
Use smaller step to scale fonts.
Rename font_desc_free function, previous name was misleading as only the cached
resources are freed.
* Add contextmenu plugin from takase
From https://github.com/takase1121/lite-contextmenu
Adapted to show font scaling commands and find/replace commands.
i# testing.lua
* Fix the cursor flickering with contextmenu
To avoid flickering of the cursor when using the context menu
we add a new function `core.request_cursor` that just take note
of the cursor requested.
The cursor will be actually changed only in root_view:draw() method
only when all the drawing operations are done. This means the cursor
will be changed only once per frame and only the most recent cursor
change request will take effect.
* Remove unneeded scale plugin return functions
On macos 11.2.3 with sdl 2.0.14 the keyup handler for cmd+w was not
enough. Maybe the quit event started to be triggered from the keydown
handler? In any case, flushing the quit event there too helped.
Use regular expressions instead of Lua patterns for find and replace editor commands.
Syntax files can now use regex or Lua patterns as before keeping backward compatibility for plugins.
In some cases rencache was using a FontDesc pointer that was actually freed by
Lua giving segfaults errors.
In addition, some FontDesc object were not freed in some cases if the
rencache_end_frame was not called when performing the "restart" command.
The invalid access problem can happen because rencache keep some pointers to
FontDesc object but these are Lua userdata that Lua can dispose of. This
situation is prone to hard errors and we should avoid to keep pointers to
objects managed by Lua.
To this purpose we use luaL_ref/unref to bind the FontDesc into the Lua's
registry while rencache need them. We still keeps pointer to FontDesc object but
using luaL_ref we are assured they will not be disposed by Lua.
Since we are using luaL_ref/unref to inform the GC about when the objects are in
use we can now finalize the objects directly when Lua collects them. Previously
the GC metamethods was issuing a FREE command to rencache and the font was
actually freed only from the rencache_end_frame function.
Introduce a new approach that discriminate coordinates in
points and pixels. Now all the logic from the Lua side and in
rencache is to always use points. The coordinates are converted
to pixels only within the renderer, in the file renderer.c.
In this way the application logic does not need to care about the
scaling of the retina displays.
For non-retina display the scaling between points and pixels is
equal to one so nothing will change.
There is nevertheless a change that leak into the Lua side. The
subpixel coordinates are in sub-pixel, not sub-points so they are
scaled by the retina scaling factor. But no change in the code is
required because the subpixel scaling factor take into account the
retina scaling, when present.
Because the retina scaling factor is not know when the application
starts but only when a window is actually available we introduce a
mechanism to render the font with a given scaling factor only from
the renderer when they are needed. We use therefore FontDesc to
describe the font information but without actually rasterizing the
font at a given scale.
Useful to draw whitespaces with alternate characters and colors
without slowing down the text rendering.
A new API is implemented. A renderer.replacements object can be created
to list the replacements.
In turns the function renderer.draw_text and draw_text_subpixel now accept
two optional arguments for replacements.
