Integrated Fwk updates in Resinsight branch up to changelist 173.
Summary of changes:
* Rewrite of cvf::OverlayItem to allow fixed user controlled positioning
of the items.
* Removed pure virtual functions OverlayItem::maximumSize() and
OverlayItem::minimumSize().
* Use caf::AboutDialog instead of modified cvfqt::BasicAboutDialog.
* Removed lapack from link line due to fail on Ubuntu 12.04 when lapack
isn't installed.
* Fix in OpenGLContext::saveOpenGLState() to avoid application
corruption when running on RedHat with VMWare.
* Removed unused font manager.
* Console assert handler only calls __debugbreak() if debugger is
present. Otherwise, calls abort(). Done after trouble running gtest
death tests.
* Made component access functions in Color3f, Color3ub, Color4f,
Color4ub inline.
* Added conversion functions between TextureImage and QImage to
cvfqt::Utils class.
* Optimized TextureImage::setPixel() - relies on new inlined
component-wise access functions for Color4ub.
* Added TextureImage::clear() and non-const version of
TextureImage::ptr().
Fields with option values implicitly have an index based
seUiValue/uiValue interface. This is commented better. Fields of AppEnum
specialization was not quite in line with the rest of the optionValue
system. That is commented and some ifdeffed code has been added to
highlight what could be done when we dare.
The setting for current OpenGL texture engine is not controlled well
enough, causing the wrong texture to be active when rendering text -
hence giving semi-random colors for the text.
