PR Summary :sparkles:

Changes seem to be revolving around the aspect of enhancing user experience, making it easier for users to engage with the tool. Let's dive into what this truly means!

• Enhanced Tooltips Appearance in Various Tools In an array of tools including Arc tools (vtoolarc.cpp, vtoolarcwithlength.cpp, vtoolellipticalarc.cpp, vtoolcutarc.cpp), Spline cut tools(vtoolcutspline.cpp, vtoolcutsplinepath.cpp), Line tools (vtoolline.cpp, vtoollineintersectaxis.cpp, vtoollinepoint.cpp, vtoolshoulderpoint.cpp, vtoollineintersect.cpp), Point tools (vtoolbasepoint.cpp, vtoolpointofcontact.cpp), and few others(doubleline_point_tool.cpp, vtoolalongline.cpp, vtoolheight.cpp), we have upped the game by beautifying the tooltips for you. Tools tips now come with improved font size and weight, making them way more readable and accessible. 🎈

• Polished Tooltips in Abstract Operations Within the files vabstractoperation.cpp and vabstractspline.cpp, we've made the tool tips more compelling to read by adjusting their font size and weight. Like a cherry on top! 🎂

No doubt, these changes are here to build up a charming and user-friendly environment for your work. So, go ahead, hover over those tools and enjoy a sleeker tooltip experience! 💁‍♀️💖
