Francesco Abbate 3109263c5d Call dmon_unwatch when changing project
Fix a conspicuous omission to call the dmon_unwatch function
when changing project directory.

This uncovered a bug or a quirk of the dmon library where the watch_ids
can change as a result of calling dmon_unwatch because they are just
indexes on a contiguous array. Use a workaround to always unwatch the
first valid watch_id N times.

Francesco Abbate cb08c5cbb7 Fix dirty pixels problem on window's right side
The last column of pixel on the window's right side isn't correctly
drawn and pixels appear dirty and more noticeably when the a NagView
message was previously shown, a stripe of red pixels remains on the right.

We use now a more souding roundig scheme. Now the rectangles to clip or to
draw are passed around as Lua numbers without any rounding. In turns, when
the rect coordinates are passed to the renderer we ensure the border of the
rect are correctly snapped to the pixel's grid. It works by computing the
coordinates of the edges, round them to integers and then compute the rect's
width based on the rounded coordinates values.

jgmdev 4188269cef Added system.rmdir(path)
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.

Francesco Abbate 752ecd5ece Group mouse move events from C API function
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?

Scale fonts context menu (#246)
* 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

Flush the SDL_QUIT event when Cmd+W is detected in SDL_KEYDOWN as well (#248)
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.

Francesco Abbate aa0b2bb5fc Fix crash problem with rencache and font access
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.

Francesco Abbate 46c3bdea67 First implementation of scaling for retina display
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.

Francesco Abbate 3426bc5d73 Introduce subpixel text positioning within rencache
In order to fix the issue with cursor positioning a subpixel-aware draw
text operation within rencache was required.

With this modification the cursor positioning problem is completely
resolved.

A new function renderer.draw_text_subpixel is introduced to perform
consecutive, inline, text drawings with subpixel accuracy.

Francesco Abbate 9ff6a0325e Mostly fix problem of offset with cursor positioning when using mouse
In order to get right the cursor position on text on mouse clicks it is
needed to take into account text's subpixel positioning.

This fix mostly corrects the problem but cursor positioning is still
somewhat inaccurate for long lines due to repeated commands to draw a text
along a line. Repeated draw text calls make the subpixel information
lost and small errors will add-up.
