Shaders: suffix all existing shaders with GL. To make room for Vulkan shaders. Also renaming the headers, of course everything is still aliased to the old names (and marked as deprecated).

Shaders: implement object ID texture visualization in MeshVisualizer. Hah this took a while, as there was no texture scaffolding in place at all. Thus all this had to be added and tested for the first time: * 2D textures * 2D texture arrays * Texture transformation uniforms * Texture transformation UBOs * Instanced texture offset This also means that MeshVisualizer can be used to visualize arbitrary (single-channel) integer textures now, not just render meshes with object ID textures. Yay for feature parity!

/* InstancedObjectId and ObjectIdTexture are a superset of ObjectId so only

Shaders: add missing MeshVisualizerGL*D::setObjectId(). Originally the uniform wasn't present with the assumption that users could easily adjust color map offset to achieve the same effect. That was however unnecessarily annoying and error-prone in cases where it's essential to have the same object IDs from multiple draws have a matching color, and it was complicating multidraw workflows as the color map offset was not a part of per-draw data, but rather material data.
