* New custom widget for EAlphaBlendOption properties showing a combo box with the curve graph and name inside it. Once clicking on it, a borderless overlay window will be opened showing a grid of available curve types (like in Sequencer). * Refactor: Separated the easing customization into a grid compound widget that shows the curve types and the actual customization. * The grid widget holding the curves now has a filter, to exclude unsupported curve types for various situations. (e.g. we do support more easing curve types than we do for alpha blends in state transitions). * Created a new compound widget that shows a curve and the name below it, which is used as button content for the new combo box. * Curve types use grouping set in the enum. Testing: * Made sure the easing curve type menu in Sequencer works the way it worked before. * Made sure the blend modes in the state transitions and e.g. a blend poses anim graph node works the same way as before. #jira: https://jira.it.epicgames.com/browse/UE-166261 Initial slack channel discussion: https://epicgames.slack.com/archives/C044VB3LCKX/p1664989593947499 Continued slack thread: https://epicgames.slack.com/archives/C0450453V6J/p1665577875211299 #preflight 63578cdef726e94fe038af63 [CL 22746945 by benjamin jillich in ue5-main branch]
