* eglfs: implement hardware cursor for the raspberry-piGirish Ramakrishnan2012-06-011-20/+37
| | | | | | | | | | | | | | | | The cursor is rendered on a dispmanx layer and moved around. This approach saves us from having to update the underlying window each time the cursor moves. Dispmanx layers cannot be moved to negative coords. As a result, currently it is not possible to move to a location less than the hostpot. A future commit will fix this problem.

* eglfs: use GL API directly in QEglFSCursorGirish Ramakrishnan2012-05-251-11/+51
| | | | | | | | | | | | | | | | | | | | | The upcoming hardware cursor support for pi requires the cursor code to render with it's own context. This is because the cursor rendering happens in the input event (gui) thread which may be different from the the scenegraph thread. Currently, Qt can be informed about the current opengl context by using QOpenGLContext::makeCurrent(). All of Qt's helper OpenGL classes complain if that function has not been called. Usage of makeCurrent API requires a QSurface. A big rewrite of EGLFS is needed to make such a QSurface (QEglFSWindow) available to the cursor code. There is no other way around this since Qt has no other API to inform it that an opengl context is active. The solution is not use Qt's OpenGL helper classes and use GL API directly.
