isES() becomes isOpenGLES(). The library type enums are changed DesktopGL -> LibGL and GLES2 -> LibGLES. This removes the now unnecessary version number, the confusing "desktop" term and provides better readability. The old function/values are kept until the related qtdeclarative changes are integrated. Task-number: QTBUG-38564 Change-Id: Ibb0a1209985f1ce4bb9451f9b7b093c2b68a6505 Reviewed-by: Sean Harmer <sean.harmer@kdab.com>
