v0.15.1-gpu_2d-rendergraph_visualizer

This release brings a GPU-accelerated 2D rendering context, improved modularity in build scripts, support for Raspberry Pi 5, an interactive rendergraph visualizer, and support for a new shader language, Slang.

New (Highlights)

• c18df00 implement explicit setters for shader argument bindings via set, binding, additionally to name-based lookup
• 9a3b001 add demo for rendergraph_visualizer to compute example
• c3dbf89 update vulkan version to 1.4.328 (you might want to set this to 1.3 for Raspberry Pi 5 in le_instance.cpp)
• bbcc6b0 update tracy to latest version
• 28f815d add support for Slang shader language & infrastructure
• 4d620f9 add hlg eotf and oetf color transfer functions (useful for hdr rendering)
• 79b3c49 update build file infrastructure to use CMake minimum version 3.29
• 8ababe6 add interactive rendergraph visualizer
• 95d71df [backend|renderer] implement component swizzle for image views - this allows you to declare texture samplers that swizzle while sampling
• 757d1a5 [le_path] implement natural cubic bezier interpolation for closed subpaths
• 9e7e70e [le_path] implement natural_cubic bezier interpolation for open subpaths
• f9d8f44 [le_timebase] implement get_seconds_since_last_frame - a convenience method that returns seconds since last frame
• 133699f [le_path] implement iterator for le_path
• 287e97a [renderer] implement compute shader fillBuffer command
• 457f29a [renderer] implement dispatchIndirect command
• e93ddd3 [le_path] add get_polyline_tangent_at_pos_interpolated
• f0a216e [le_path] add methods to query polyline distances
• d94f8d2 [rpi] add support for Raspberry Pi 5
• db71235 [ffmpeg_pipe] add module useful for rendering to ffmpeg

Changes (Highlights)

• 556ac6b [BREAKING] prefer binding name over binding type name when resoving glsl shader binding names
• 971ea18 refactor shader compilation infrastructure: shaders are compiled lazily
• 7857bfd shader compilers use shared interface (this allows adding future shader compilers as plugins, similar to le_resource_manager handles image format adapters)
• 27063e8 add more output pixel formats to ffmpeg-pipe
• cebe519 make swapchains ColourSpaceKHR aware
• 1172ef7 fixed a memory issue when using le_font
• 902fcaa [debug_print_text] set default background to 30% black
• aba56eb [core] expose spookyhash methods so that they can be used via le_core
• 6088c0b [le_font] update stb_truetype to v1.26
• e02b7c7 [rendergraph] make setup callbacks one-shot
• 35a4c67 [renderer] refactor encoder
• 9f2d5de [backend] update vma_mem_alloc to 3.3.0
• 774d45b [build] set glm defines via cmake globally
• f72fc86 [le_path] rename contour -> sub_path
• d7a1d89 [BREAKING] [le_path|le_2d] unify control points order for svg-style path commands
• 68868e4 [le_2d] remove old le_2d
• 6295ff9 [3rdparty] update to latest version of glm
• 129c25f [*] refactor LE_SETTING: setting may have name independent of its variable name
