Chip Davis	056c0e207d	Take the vertex count from any indirect parameters passed. ... This is necessary to deal with indirect draws, where the draw parameters are given in a buffer instead of passed by the CPU. For normal draws, the draw parameters are set with Metal's `setVertexBytes:` method. This undoes the change to add the vertex count to the aux buffer, rendering that entire discussion largely moot. Oh well. It was a discussion that needed to happen anyway.	2019-02-06 15:17:14 -06:00
Chip Davis	c51e5b7911	MSL: Add a setting to capture vertex shader output to a buffer. ... This will be necessary to support transform feedback, as well as tessellation shaders.	2019-02-05 20:00:10 -06:00
Chip Davis	f500d2f70c	MSL: Hoist fixup hooks in entry_point_args() out of the compile loop. ... Otherwise, in the event of a forced recompile, we could end up adding them twice.	2019-01-17 10:18:38 -06:00
