Calling X11 window system is superfluous for headless rendering. This patch
implements EGL platform using GBM, which is slightly more simple than the GLX
path when using X11.
In principle there are no big advantages in terms of performance etc. My
motivation behind this was to get in touch with the code and the project. For
testing I'm using:
$ unset DISPLAY && ./build/linux-x86_64/Debug/mbgl-test
v2: rebased patch against the new cmake changes; walk through render node to
find a valid one; remove EGLSurface completely cause windows are not needed
here.
This is safer now -- it can be an implementation detail of Segment/Context. And the typing of SegmentVector now ensures that the attributes and program match.
Two reasons to prefer explicit sequential location assignment, rather than relying on the GLSL linker to assign locations:
* For data-driven properties, we want to have the option to use glDisableVertexAttribArray plus glVertexAttrib*. In order to use glDisableVertexAttribArray, we must avoid using attribute location 0, which cannot be disabled.
* We want to use the same VAO in cases where, say, a fill layer might be rendered with FillProgram at first, and then FillPatternProgram later. VAOs do not store the program binding, only the attribute bindings, so as long as the two programs have the same attributes and attribute locations, only a single VAO (per segment) is needed.
* [core] Line-break ideographic text by character
Allow a line break to be inserted after any supported Chinese, Japanese, or Yi character in a point-placed label. Balance the lines unless non-ideographic text such as Latin letters are present.
Fixes#1223.
* [core] Moved more character classing into util::i18n
* [core] Detect character properties by Unicode block
* [test] Reenabled ideographic breaking tests
* [android] - getMarkerViews in rectangle should only return in bound views.
* added example in test app for debugging
* Covert rectangle coming in to density dependant rectangle
When a source or layer is removed transfer ownership back to the
caller so it can (optionally) take it. Preserve the behavior that
removing a CustomLayer triggers deinitialization. Deinitialize all
custom layers when a style is destroyed in case those layers are not
explicitly removed.
