Implement the HSL filters (called "non-separable blend modes" in the spec).
...
These cannot be implemented with the standard OpenGL blending functions, so we
have to do them manually in a shader, which requires a good deal of machinery
to create intermediate framebuffers and so forth.
2020-02-24 15:37:44 -08:00
67d12adb6c
Replace layers with render targets, which can be used as patterns.
...
This allows us to efficiently handle a lot of workloads that require multiple
HTML canvases, without CPU readback. For example, you can render paths to a
render target, then turn that render target into a repeating pattern that you
fill other paths with. Or you can render paths to a render target and then
composite that render target as a whole with a blend mode.
This introduces a new `DrawRenderTarget` render command that blits a render
target without any paths involved. This is basically just a hack that works
around the fact that our tiled renderer doesn't yet support effects that widen
the ink region (i.e. blurs). It can be removed once we have that support.

Fix vertex attribute configuration of alpha tiles.
...
Fixes #134 .
glVertexAttribPointer takes a size as parameter which refers to the number of components and not the size in bytes of the value.
The tile index was registered as a 2-components value which caused the second component to overlap with the first member of the next primitive, which was mostly fine except for the last element which would overlfow the buffer. Intel and nvidia GPUs/drivers on linux at least refuse to read the first component of this two-component value if the other component is outside of the valid range which caused the shader to get zero instead and always select the first mask tile.
