Review request for Calligra, Dmitry Kazakov and Boudewijn Rempt.


Repository: calligra


Description
-------

KisOpenGLImageTextures::updateTextureFormat() some weeks ago got extended with code using variables (`colorModelId`, `destinationColorModelId`, etc) only declared inside an area guarded with `#ifdef HAVE_GLEW`. Which results in the compiler giving up with building when `HAVE_GLEW` is not defined.

Attached patch removes that reason for the compiler to be lazy, but I have not enough insight if that makes sense, so need your input.

Together with https://git.reviewboard.kde.org/r/120469/ applied Calligra/Krita builds without GLEW headers installed, and Krita starts up and works for the little bit I tested. Just the mouse cursor/brush is not seen over the canvas.
