Refactor Instanced Drawing to use Vertex Arrays Per-instanced data was previously stored in uniforms. This required several OpenGL calls to upload all of the data, and it was more complex to prepare (several vecs vs one). Additionally, drawing APIs are now accessible through a `RenderApi` (obtained through `QuadRenderer::with_api`) which enables some RAII patterns. Specifically, checks for batch flushing are handled in Drop. 2016-06-06 20:20:35 +00:00			`in vec3 fg;`

Correct sub-pixel font rendering with OpenGL Uses the GL_ARB_blend_func_extended to get single-pass, per-channel alpha blending. gl_generator is now used instead of gl to enable the extension. The background color is removed since that presumably needs to run in a separate pass. 2016-05-21 04:36:28 +00:00			`layout(location = 0, index = 0) out vec4 color;`

Bit of cleanup - Commend vertex slice - Add helper for binding mask texture (and specify that it's a mask) - Prefix uniform members of ShaderProgram with u_. This makes it easy to identify in the rest of code. 2016-02-25 04:37:17 +00:00			`uniform sampler2D mask;`

Initial support for Terminal Emulation (woo!) This patch introduces basic support for terminal emulation. Basic means commands that don't use paging and are not full screen applications like vim or tmux. Some paging applications are working properly, such as as `git log`. Other pagers work reasonably well as long as the help menu is not accessed. There is now a central Rgb color type which is shared by the renderer, terminal emulation, and the pty parser. The parser no longer owns a Handler. Instead, a mutable reference to a Handler is provided whenever advancing the parser. This resolved some potential ownership issues (eg parser owning the `Term` type would've been unworkable). 2016-05-31 03:44:37 +00:00			`alphaMask = vec4(texture(mask, TexCoords).rgb, 1.0);`
