Add GskGLShaderNode and GskGLShader A GskGLShader is an abstraction of a GLSL fragment shader that can produce pixel values given inputs: * N (currently max 4) textures * Current arguments for the shader uniform Uniform types are: float,(u)int,bool,vec234) There is also a builder for the uniform arguments which are passed around as immutable GBytes in the built form. A GskGLShaderNode is a render node that renders a GskGLShader inside a specified rectangular bounds. It renders its child nodes as textures and passes those as texture arguments to the shader. You also pass it a uniform arguments object. 2020-09-18 15:46:57 +00:00

gsk: Deprecate GskGLShader and the rendernode The new renderers don't support them due to the required complexity of integrating them with Vulkan and the assumptions those nodes make about the renderer (the GL renderer exports its internal APIs into the GLShader). There haven't been any complaints that I'm aware of since 4.14 was released where the default renderer does not support the nodes, so usage in public seems to be close to nonexistant. The 2 uses I know of were workarounds about missing features in GTK that have stopped since GTK now supports them: 1. GStreamer used in to do premultiplication when the old GL renderer did not do so in hardware but on the CPU. 2. Adwaita used it for masking before the mask node wa added in 4.10. 2024-07-04 16:12:16 +00:00			`G_GNUC_BEGIN_IGNORE_DEPRECATIONS`
