Now otclient lightning may look like more tibia lights,
before this too many lights together would increase
brightness a lot, this won't happen anymore in cards
with OpenGL 1.4 or newer
* Fix recursive reference memory leak in UIWidget
* Make Event/ScheduledEvent memory-leak safe
* Fix exit crashs by freeing graphics resources before destroying GL context
* Add many asserts to avoid any leak regression
* option to pass -opengl1 or -opengl2 as argument
* note that with this commit there are a lot of graphics regressions and the master will remaing unstable for a while
* shaders disabled for a while
* implement draw clipping using opengl stencil buffers
* allow to create Widgets by style name with g_ui.createWidgetByStyle
* styles can now have children widgets
* make proper use of the isNotPathable in pathfinding
* add scrollbar skin
* zooming without real FBOs kinda works, but with lower quality
* hardware detection for glGenerateMipmaps
* possibility to disable bilinear filtering, mipmaps, framebuffers, and realtime mipmap generation in g_graphics
* otclient works well using 3D acceleration in VirtualBox again
* many fixes regarding FBOs fallback implementation
* use OpenGL 2.0 auxiliary buffers when FBO is not supported, thus this means that OpenGL 3 is not a requirement anymore, so otclient might work in older video cards
* map zooming will never work well with Opengl 2.0 because of glCopyTexSubImage2D limitation
* rework client modules
* hide main window when loading
* remake top menu functions
* rework modules autoload
* improve path resolving for otml and lua
* move core_widgets to core_lib
* fix tooltip issues
* split some styles
* add bit32 lua library
* fix assert issues
* fix compilation on linux 32 systems
* rework gcc compile options
* renable and fix some warnings
* remove unused constants
* speedup sprite cache
* move UIGame to lua (not funcional yet)
* fix a lot of issues in x11 window
* fix crash handler
* add some warnings do uiwidget
and much more...
