* Fixed a small graphical mispositioning in rendering of keyword abilities.
* Added an option to hide set symbols entirely when rendering.
* Fixed flip walkers like Arlin Kord showing a "0" loyalty on their back face (when they should have no loyalty there).
* Removed some log files I accidentally committed.
* Fixed a bug in tokens, where they are missing their expansion symbol of they are created by another token
* Fixed the the new Rendering based CardPanel not returning the correct Image through getImage (resulting in a poor quality image in the card preview window)
In most cases, it is not useful to hold priority after doing something,
since the spell or ability added to the stack can just be performed
beforehand.
Hence, automatically passing priority is the only comfortable setting.
However, in some cases it is useful (chiefly for Infernal Tutor +
Lion's Eye Diamond and similar interaction), and currently players
have to open Preferences, change the option and then change it back
whenever they need to hold priority, which is very annoying.
This change allows to temporarily hold priority by simply holding
Control while performing an action, which solves the issue in a
manner similar to other clients.
A "Hold" indicator next to the spells cast indicator is displayed so
that the user knows his Control key holding was registered.
The code works by adding a new HOLD_PRIORITY player action that causes
the automatic priority pass options to be ignored until the player is
given priority again.
The client sends the message whenever it's not already holding priority
and Ctrl+click/space/enter happens anywhere.
This is somewhat "loose" as it means that Ctrl+click on the background
also holds priority, but this might actually be desirable and it greatly
simplifies the code, since only a global AWT event listener is required,
and there is no need to change every place in the code that could add
something to the stack.
It is also possible to hold priority and stop holding priority using
the context menu.
Skips everything until next turn, except for declare attackers and blockers.
F11 and F9 are a better design, but F6 is provided for compatibility with
established conventions.
There is currently no GUI button for it.
All the current behavior of ScaledImagePanel seems to be useless, since the source
images are static, so we can just use the highest quality scaling possible and
cache the result using TransformedImageCache.
RotatedResizedImageCache and MultiRotatedResizedImageCache contain the caching
machinery.
A cache of rotated and resized images is added to ImageCache, and is used by
the resizing functions there.
All the resizing and rotation functions in ImageHelper are redirected to the
ones in ImageCache.
This is slightly inefficient because it will cache some calls that are never
repeated, but it prevents developers from mistakenly using uncached functions
when calls are repeated, seriously impacting performance.
Also resizing functions that only take a width or an height have been removed,
and their calls fixed to provide the other dimension. It's still possible to
specify -1 as width or height to ignore constraints in that dimension, though.
Greatly speeds up UI performance.
