This is an huge refactor to avoid handling Allegro FONT directly. Some
changes:
* Add she::System::defaultDisplay/Font, createRgbaSurface, loadSurface,
and loadRgbaSurface.
* Rename she::CreateSystem/Instance to she::create_system/instance.
* Remove ui/font.cpp and move ui/fontbmp.cpp to she library.
* ui::IButtonIcon uses she::Surface instead of BITMAP.
* Rename she::LockedSurface::drawAlphaSurface -> drawRgbaSurface
* Rename ui::SetDisplay -> set_display
* Rename _ji_font_text_len -> ui::Graphics::measureUIStringLength
On Windows, instead of polling Allegro mouse position/buttons we can use
the mouse messages (WM_*) directly to generate she::Events. Those events
are received by the ui::Manager and converted to ui::Messages.
Maybe this is a possible fix for issue #133 (Wacom tablets don't work
properly).
Changes:
- Don't use jmouse_z() directly (new ui::MouseMessage::wheelDelta() member)
- Add ui::_internal_set_mouse_position() to change the jmouse_x/y(0)
from the new mouse position received in she::Events. The same for
ui::_internal_set_mouse_buttons().
- Modify the ui::Manager to generate mouse events in any case: using old
Allegro 4 polling method, or from she::Events.
- Add HAVE_CONFIG_H wrapper to #include "config.h"
- Removed widgets namespace (it's in app now)
- Move some functions from src/file/file.h to src/base/cfile.h
- Move Vector2d to base library
- Rename MenuItem2 to AppMenuItem
