AggPas hybrid canvas with native font rendering — now the default in fpGUI

[graemeg]

In preparation for the upcoming v2.1.0 release (and some exciting surprises still to be revealed!), the default fpGUI canvas is now the hybrid canvas. It uses AggPas for all 2D rendering, with FreeType handling font rendering and metrics on Linux, FreeBSD, and macOS. On Windows, the native GDI font engine is used — which means no more freetype.dll dependency required. 🎉

Build instructions have been greatly simplified too. The README has been updated with the full details, but in short:

# Linux & FreeBSD
pasbuild compile -p unix

# Windows
pasbuild compile -p windows

# macOS
pasbuild compile -p macos

That's it — no extra profiles needed!
