GPUShader: Add selection id shader This is to separate id drawing from standard color drawing. 2018-12-22 21:02:30 +01:00

3D View: Move selection API to a Selection engine. This commit moves the API of selecting faces, vertices and edges to a DRW manager engine.

Fix T68911: "illegal recursive expansion of macro id" I imagined that could be a problem for some drivers. I should have avoided. 2019-08-20 21:56:39 -03:00			`# define _id floatBitsToUint(intBitsToFloat(id))`

GPU: Simplify select shaders. The shaders are: `GPU_SHADER_3D_FLAT_SELECT_ID` and `GPU_SHADER_3D_UNIFORM_SELECT_ID`. This commit allows the drawing of the mesh select ids to be done on a 32UI format texture. This simplifies the shader that previously acted on the backbuffer and had to do an uint to rgba conversion.
