remove unecessary files
update shaders PR, remove comments
bump test suite sha
fix formatting, incorporate feedback
refactor program.hpp
* [core] remove line transformations that were moved to the shaders, bump shader sha
* [core] shorten ProgramParameter instantiation
* [core] bump shader+test suite shas
* Extract `ignore` util to separate header.
* `Segment` now tracks offset and length of indices, rather than primitives. This is more natural.
* Introduce `VertexVector` and `IndexVector` types. These types carry information about the intended draw mode (`Triangles`, `LineStrip`, etc.), and ensure that elements are always appended in a group size appropriate for that draw mode, for both indexed and unindexed rendering.
* `Program`, rather than `Drawable`, is now the unifying object for draw calls. `Program` is the best place to type check the draw call, because it is typed to carry information about the intended primitive, vertex type, attributes, and uniforms.
* Use the debug shaders for debug tile rendering, like gl-js.
* Fix the draw mode for background. It was drawing triangle strips with a triangles array. Surprised this didn’t cause issues. Now it’s type checked.
We are using Value::reset() to change a piece of GL state to its default value. However, the current implementation always executes the GL call, even if our state tracking system knows that it's already at that value. The new implementation of Value::reset() now respects that, resulting in a lot fewer GL calls.
- Use glBindAttribLocation for GLSL attributes.
- Create a separate shader for each shader that supports overdraw.
Needed because each uniform location must be known for every program.
- Create a separate VAO for each shader inside buckets.
Needed because we can only bind a VAO to a specific shader.
Fixes#5435.
