2016-03-16OPENGL: Resolve OpenGL functions on run-time.Johannes Schickel
Formerly we relied on static linkage. However, in the presense of modern OpenGL (ES) implementations it is not easily identifable which library to link against. For example, on Linux amd64 with nVidia drivers and SDL2 setup to create a GLES 1.1 context one would need to link against libGL.so. However, traditionally GLES 1.1 required to link against libGLESv1_CM.so. To prevent a huge mess we simply resolve the OpenGL functions on run-time now and stop linking against a static library (in most cases). GLES support needs to be enabled manually on configure time for now. Tizen changes have NOT been tested.
2014-01-21OPENGL: Properly query for OpenGL errors.Johannes Schickel
There might be various error flags and we need to clear all of them to get precise error results. Thus, we need to call glGetError in a loop to achieve that.
2013-10-19OPENGL: Add new generic OpenGL (ES) backend.Johannes Schickel
This backend is based on ideas of the old OpenGL backend, of the Android GL backend and of the iPhone GL backend.
