renderer: create explicit sampler state for custom shaders

renderer: create explicit sampler state for custom shaders The GLSL to MSL conversion process uses a passed-in sampler state for the `iChannel0` parameter and we weren't providing it. This magically worked on Apple Silicon for unknown reasons but failed on Intel GPUs. In normal, hand-written MSL, we'd explicitly create the sampler state as a normal variable (we do this in `shaders.metal` already!), but the Shadertoy conversion stuff doesn't do this, probably because the exact sampler parameters can't be safely known. This fixes a Metal validation error when using custom shaders: ``` -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation Fragment Function(main0): missing Sampler binding at index 0 for iChannel0Smplr[0]. ```

Framebuffer.zig
renderer: big rework, graphics API abstraction layers, unified logic This commit is very large, representing about a month of work with many interdependent changes that don't separate cleanly in to atomic commits. The main change here is unifying the renderer logic to a single generic renderer, implemented on top of an abstraction layer over OpenGL/Metal. I'll write a more complete summary of the changes in the description of the PR.

Texture.zig
renderer/opengl: explicit texture options This sets up for a couple improvments (see TODO comments) and also sets the glyph atlas textures to nearest neighbor sampling since we can do that now that we never scale glyphs.
