2018-07-06gl: Multi-line labels.Tor Andersson
2018-07-05Pass rect and matrix by value in geometry functions.Tor Andersson
Several things irk me about passing values as const pointers: * They can be NULL, which is not a valid value. * They require explicit temporary variables for storage. * They don't compose easily in a legible manner, requiring weird pointer passing semantics where the variable being assigned is hidden as an argument in the innermost function call. * We can't change the value through the pointer, requiring yet more local variables to hold copies of the input value. In the device interface where we pass a matrix to a function, we often find ourselves making a local copy of the matrix so we can concatenate other transforms to it. This copying is a lot of unnecessary busywork that I hope to eventually avoid by laying the groundwork with this commit. This is a rather large API change, so I apologize for the inconvenience, but I hope the end result and gain in legibility will be worth the pain.

2018-06-22gl: Add layout packer and various widgets.Tor Andersson
* Move window setup and swap buffer calls into ui_begin/end. * Rearrange source files. * Simplify grab logic: Make it more robust in the face of user errors, such as setting ui.active to NULL explicitly. * Copy text to primary selection as well.
2017-11-08gl: Remove GLFW and reinstate FreeGLUT.Tor Andersson
GLFW doesn't build on Visual Studio 2005 anymore, and I don't have time to keep up with the changes. So, we're switching back to FreeGLUT, which is more stable. I've added the two missing features that made us switch to GLFW in the first place: input methods and system clipboard support. If MuPDF is compiled with our version of FreeGLUT, we now use these functions: * glutKeyboardExtFunc * glutSetClipboard * glutGetClipboard
