[Feature request] Find a way for easier pixel format selection

[bartlomiejduda]

Some users reported that there are too many pixel formats to choose from and it became hard to find correct pixel format on the list.

Proposed solutions:

• Searchable combobox
• Grouped pixel formats (ability to apply group filter)

One of the solutions should be implemented to solve the issue.

The palette format box could use this too, as being able to type either the leading characters (or a substring) would greatly accelerate selection, kinda like the Windows Run dialog.
