* use smart pointers for almost all widget fields
* use SDL2 texture for cursor
* a lot af small tweaks and formatting
* removed CompImage class, it is actually useless as long as regular SDLImage support margins
* CGuiHandler: use smart pointers for [push|pop]Int
* margin option .json animation
* Use ranged attack animation for spell cast if there is no cast animation, display cast animation only on active casting.
Long time ago it's was used without prefix to make future switch from boost to std version easier.
I discusses this with Ivan and decide to drop these using from Global.h now.
This change wouldn't break anything because there was already code with prefix for each of three cases.
- UI will be correctly greyed-out during opponent turn
- fixed remaining issues with blit order
- a bit better handling of catapult attack
- fixes#1362
- removed unused functionality from CCreatureAnimation
- simplified postioning of units in battle, should fix remaining issues with unit positioning
- fixed unit tests compilation
- speed of creature-related animation no longer depends on framerate
- most of values from cranim.txt are now used correctly
- removed BMPPalette struct in favor of SDL_Color
- animation group "DEAD" that is used to display dead stacks, by default consists from last frame of "DEATH" group
Notes:
- animation speed may still need some adjustments
- range of config property "battle/animationSpeed" has been changed. This may result in extremely fast animation. To fix - change animation speed via options.
- use std versions of function, bind and ref
- OVERRIDE -> override
- NULL -> nullptr
- use std versions of random distributions
NOTE: this may be last revision that supports gcc-4.5
