2016-11-04opengl: move shaders to its own directoryTomaž Vajngerl

2016-05-23opengl: combined shaders to reduce shader switchingTomaž Vajngerl
Combine most common shaders for non-texture drawing and texture drawing into two combined shaders. Inside the shader we switch between the code paths with if statements. Using if statements (or any other branching statements) is discouraged inside shaders but on the other hand we reduce program state changes if we have less shader changes - which is more important for us as we want to push more work to the GPU.

2016-02-25opengl: shader based polyline rendering - fixes tdf#97137 for OGLTomaž Vajngerl
Adds native opengl polyline rendering to draw polylines, line joins and line caps as triangle strips. The vertex shader allows for the dynamic line width by calculating the correct vertex posiitons, and the fragment shader is used for anti-aliasing.

2015-09-01Added support for computing 64-bit checksum of bitmap in OpenGLMarco Cecchetti
Added a C++ and a GLSL implementation of a 64-bit CRC algorithm. Changed hardcoded checksum value in ooxmlimport unit test (testN777345). Change-Id: I16bb985a14866775efda49e21fe033ff64645896
2015-08-24opengl: push mask coords to the shaders along the image coordsTomaž Vajngerl
If using the same texture to store the image and mask data (for example when using texture atlas) the mask and image (RGB) coords aren't the same anymore. With this commit we always define the mask coords separately. Change-Id: Ie33f87a6e9ab398972c6a3d5938e5f1364c82d36
