License headers: add SPDX licenses for '.glsl' files When GLSL sources were first included in Blender they were treated as data (like blend files) and had no license header. Since then GLSL has been used for more sophisticated features (EEVEE & real-time compositing) where it makes sense to include licensing information. Add SPDX copyright headers to .glsl files, matching headers used for C/C++, also include GLSL files in the license checking script. As leading C-comments are now stripped, added binary size of comments is no longer a concern. Ref !111247 2023-08-24 10:54:59 +10:00			`/* SPDX-FileCopyrightText: 2017-2022 Blender Authors`

Selection: Add conservative rasterization to select really small objects The conservative depth shader is ~4.5x slower than the normal one as it uses geometry shader and fragment shader discard. This patch also includes a hack to also fix the view parallel planar geometry and the really small wire objects. For some reason, the conservative raster fix does not work with normal selection but does with box select. This is a fix for T63356.

Pointcloud selection support This patch adds support for selecting pointclouds. Since pointclouds were not properly drawn to the selection buffer (as diagonsed by output from `glReadPixels` and Renderdoc), they were not able to be selectable by depth picking or occlusion queries. In `basic_engine`, objects were rendered with a shader which draws to a depth buffer but only assumes a single position vertex attribute. Pointclouds, though, require at least another vertex attribute `pos_inst` which provides the instance offsets. Thus, this patch adds another shader variant for pointclouds which supports these two attributes and renders the points appropriately. {F11652666} Addresses T92415 Reviewed By: fclem Differential Revision: https://developer.blender.org/D13059 2021-11-01 11:24:50 +01:00
