* [core] allow context to be abandoned on destructionIvo van Dongen2017-09-222-1/+9

* Preserve depth buffer between 3D layers + optimize render order (#9931)Lauren Budorick2017-09-212-1/+18
| | | Port of https://github.com/mapbox/mapbox-gl-js/pull/5101: adds a new render pass `Pass3D` before any other rendering wherein we render layers with 3D passes (fill-extrusion layers) to offscreen framebuffers, sharing a depth renderbuffer between those layers in order to render 3D space correctly. Those framebuffers are saved on the RenderLayers and copied back to the map during the translucent pass. Rendering to offscreen framebuffers before we do any clear + draw means we can avoid expensive framebuffer restores.

* [core] Dirty the correct state when a texture is deletedJohn Firebaugh2017-09-111-2/+4
| | | | When a texture is deleted, it is as if all texture units to which that texture object is bound are rebound to texture object zero. Therefore it's the *bindings* that need to be dirtied, not the active texture unit.

* [core] Rework attribute binding (again)John Firebaugh2017-07-1214-245/+226
| | | | | | | | | | 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.

| | | | | | | | | | 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] Bind only active attributes in order to avoid exceeding attribute ↵Lauren Budorick2017-06-293-6/+64
| | | | | limits (#9373) Introducing two new attributes to enable property functions for line-width (#9250) pushed the attribute count over GL_MAX_VERTEX_ATTRIBS on some devices. Now we selectively bind only attributes that are used, making it unlikely to surpass GL_MAX_VERTEX_ATTRIBS.

* [core] store vertex attribute binding to prevent duplicate bindsKonstantin Käfer2017-06-131-0/+1
| | | | | | | | | We have an "oldBinding" value that we use for checking whether the vertex attribute was already bound to the current VAO, but we never set the state. Additionally, we're also checking whether the previous state was already any binding (optional is set), and don't re-enable the vertex attribute array. Additionally, we now only disable the vertex attribute array when the previous state was in fact an array attribute. We still don't deduplicate constant glVertexAttrib* calls, but that's a little trickier.

| | | | | | | | Previously, we initialized global variables that held pointers to the extension functions.

Therefore, we are now making them a member variable of the Context object.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
