* [core] Rework attribute binding (again)John Firebaugh2017-07-126-35/+108
| | | | | | | | | | These changes are necessary for programs whose set of active attributes is not fixed at compile time by a template parameter pack, but rather varies based on the generated shader text at runtime. In such cases, the attribute location of a given named attribute may vary between instances of the same Program. Previously, attribute bindings were implicitly associated with a location based on template parameter order, and -1 was used to indicate an inactive attribute. This left us unable to disable the appropriate attribute when it went from active to inactive. Now, the state tracker for bindings explicitly associates locations and state, and an empty optional is used to indicate an inactive attribute. In addition, a gl::VertexArray class is now exposed, allowing more flexibility in the relationship between Programs, Segments, and attribute bindings. In this commit, that relationship does not change, but the subsequent commit adjusts it to match gl-js, reduce rebinds, and work around buggy VAO implementations. VertexArray uses a pimpl idiom in order to support implementations that lack the VAO extension. In that case, all VertexArrays share global binding state, reflecting the platform reality in the absence of VAOs, while still providing a uniform API.
* [core] Update shaders.Chris Loer2017-07-122-1/+16
| | | | | Implements 'icon-pitch-alignment' (issue #9345) Fixes issue #9456 (map-aligned point label regression)

* [core] improve legibility of labels that follow linesAnsis Brammanis2017-07-114-137/+107
| | | | | | | | | | port https://github.com/mapbox/mapbox-gl-js/pull/4781 This improves legibility of labels that follow lines in pitched views. The previous approach used the limited information in the shader to calculate put the glyph in approximatelyright place. The new approach does this more accurately by doing it on the cpu where we have access to the entire line geometry.

* [core] Don't use "current" icon/text-size when bindingJohn Firebaugh2017-06-141-16/+5
| | | | | | The current value is not passed to `SymbolSizeBinder::uniformValues`, so we shouldn't check `currentValue.isConstant()` in `SymbolSizeBinder::attributeBindings`. If it were true, then we might end up using attribute bindings that are appropriate only for a constant property, but uniform bindings that are appropriate only for a source or composite function. Instead, just wait for a new bucket to be generated. This will happen automatically, since icon/text-size are layout properties.

| | | | We switched to 16-bit coordinates in attributes in b0cb8715ed74678b4d0f05829fa71a590e41b2f6, so there's no longer any reason to require that they are divisible by four.

* [core] Fix overspecialization of PaintPropertyBinder templateJohn Firebaugh2017-03-171-143/+38
| | | | | | | | | | | | | | | | | | PaintPropertyBinder and subclass templates were being instantiated for every unique attribute type (e.g. a_color, a_fill_color, a_halo_color) even though they behave identically for a given property value type (e.g. Color). To fix this, a unique type such as a_color no longer derives from gl::Attribute<...> -- instead it has an inner Type typedef, which should be used wherever neither a unique type nor attribute name is required.
