This is the first step to create a bigger BrushPopup to select brushes
from an history of brushes. The general idea is to use Alt+1, Alt+2, etc.
to select different brushes from a stock.
Also the "discard brush" was removed. As the brush can be discarded
changing the brush type.
With this we can see the exact preview in real-time of the the left
click paiting (e.g. using real Indexed composition, ink, point shape, etc.)
We are able to preview blur, eraser, or flood fill preview too (anyway
these are not enabled at this moment).
Changes:
* Add render::ExtraType enum to indicate if the extra cel acts like a
patch for the current cel (e.g. cursor), or as an extra layer for
composition (e.g. selection/moving pixels)
* Add ExtraCelType property to app::Document and to render::Render
* Add ToolBox::getPointShapeById()
* As the current cursor preview depends on the current layer, when
we change the current layer we've to update the Preview editor
with the new selected layer (now we listen to
Document:.onAfterLayerChanged())
* Add create_tool_loop_preview() and PreviewToolLoopImpl
Now the last update information retrieved from the HTTP request, is saved
in the configuration file so we can reuse it when the program is restarted.
Changes:
* Add support to compare two semvers
* Add new_version/new_url options to preferences
* Remove convert_to for base::Version (now this class is constructed from
strings only)
Now we backup 3 versions for each object. And when an object is saved
correctly on disk, a "magic number" is saved at the beginning of the file.
In this way we know that the file really represents the full object (and
a crash was not occurred in the middle of the process).
Sometimes, the Editor and Timeline widgets cannot be validated because the
document is locked (i.e. cannot be read). In these cases we can start a
timer to re-invalidate those areas again (and try to draw them when the
document is unlocked).
This is a first step to include the current selected range of layers
and frames inside the doc::Site structure. So in the future we'll not need
to know about the Timeline in commands that handle those ranges.
* UI scale is an experimental option (it needs app restart)
* We can change the Screen Scale without restarting the app now
* Hide reloading of skin data in SkinTheme::onRegenerate()
* Now setFontOfAllWidgets() is called from Theme::regenerate()
* Remove reload_default_font()
* Simplify gui_setup_screen()
