render: make GLES2 renderer optional Allow selecting whether the GLES2 renderer gets enabled. Co-authored-by: Simon Ser <contact@emersion.fr> 2021-04-09 10:48:01 +08:00			`glesv2 = dependency('glesv2', required: 'gles2' in renderers)`

render: use internal_features to indicate EGL support Instead of checking whether the wlr_egl dependencies are available in the GLES2 code, introduce internal_features['egl'] and check that field. When updating the EGL dependency list, we no longer need to update the GLES2 logic. 2022-06-24 07:20:42 +02:00			`if not (glesv2.found() and internal_features['egl'])`

render/gles2: validate shaders at build time Use glslang to validate GLSL shaders at build time. This is optional: if glslang is not found, shader validation is skipped. 2024-12-15 13:56:09 +01:00			`glslang = find_program('glslang', 'glslangValidator', native: true, required: false, disabler: true)`

render/gles2: move shaders to individual files Instead of having a C file with strings for each shader, move each shader into its own file. Use a small POSIX shell script to convert the files into C strings (can't wait for C23 #embed...). The benefits from this are: - Improved readability and syntax highlighting. - Line numbers in shader compiler errors are easier to make sense of. - Consistency with the Vulkan renderer. - Shaders will become more complicated as we add color management features. 2022-10-26 12:03:50 +02:00
