Overhaul refactor the render codebase

[JarKz]

Main concept

The current state of the code is very difficult to maintain so need refactor for easing adding new features and detecting bugs. Here below a list of the actions which need to be done before merging to main branch. It can growth by new upcoming tasks.

Tasks

• Add text ellipsis with new property
• Add Draw trait with new type DrawColor and Coverage
• Rewrite NotificationRect into BannerRect
• Fix padding by combining with border size
• Add helpful struct Offset for offsetting from top and left corners
• Add image as table in config for margin
• Add vertical and horizontal alignments for banner elements (i.e. texts, image)
• Fix large memory allocation by fonts
• Fix missing memory deallocation
• Fix font issue about glyph layout (ab_glyph have something else than expected)
• Implement Widgets and Containers like HPane/VPane for flexibility
• Make more controlled wayland-client usage instead of rough actions
