Now we can change several values (zoom, brush size, etc.) pressing a
keyboard shortcuts and dragging the mouse in a specific vector
direction (DragVector). It allows the modification of one, two, or
even more parameters at the same time (e.g. X axis to change the brush
size, Y axis the alpha value of the ink).
Incomplete version of the Lua debugger.
Some available features:
* Break in next executed instruction
* Step in, over, out
* See & navigate stacktrace
* See local variables
Some missing features:
* Breakpoints
* Eval user expressions with local variables
The UX needs some improvement yet.
Updates folder upon navigation (up, back, forward, in).
Also introduces a new button to refresh the current folder view when pressed or when hotkey pressed (F5 or ctrl+R)
Each ui::Window now can have a related native os::Window. This
connection is done through the ui::Display class added recently in
c3d52f0bbe5242923c9e38495e1be1135ca0934f.
In this way we always have an empty tile available in the drawing
process. We've also added the Tileset::firstVisibleIndex field to
change the visible index of the tile 1 so we can offset the visible
number by the user (just as a visual aid / simulate old tilesets with
index=0=non-empty tile).
Now on Windows it's more clear the different APIs to use (Windows
Pointer vs Wintab), the Wintab API works as before (generates mouse
events on WM_MOUSE message instead for each packet), and there is a
new Wintab mode to create events directly from packets (still a little
buggy with some tablets, but might be useful in other tablets to get
more precision for fast strokes).
* Now the max value in dynamics is equal to the brush size, so changing
the brush size (e.g. switching between pencil/eraser tools) will
change the max brush size (which is the most common parameter to
change)
* Added mini_slider style for min/max brush/angle values
* Fixed some issues clicking outside the dynamics popup
