- Removed usage of gdk_gl_font_use_pango_font() which is no longer in GtkGLExt Git. Radiant now compiles on Linux From Scratch using current versions of software. - As a side effect to the above, font inconsistency issues (like really large intermittent font in GL views) are gone. Font looks better too. - Changing algorithm for labeling grid view to be more robust. Uses new functions gtk_glwidget_font_ascent() and gtk_glwidget_font_descent(), and uses locally defined "cushion" variables. - In xywindow.cpp, changing stepx and stepy based on 40 pixels, not 32. When coordinate numbers are very large the labels get too cluttered. - Added calls to gtk_gl_init() and gdk_gl_init() in main(). This is recommended according to the GtkGLExt reference manual. - Tested all changes on Ubuntu 10.10 and Debian 5.0 (Lenny). TODO: - In glDrawPixels(), instead of using a 32 bit pixel with GL_UNSIGNED_INT_8_8_8_8, see if we can use an 8 bit variant where each byte defines opacity and the GL current color is used. In other words, try to use the FT_Bitmap directly without conversion. - Examine every other use of gtk_glwidget_print_string() and gtk_glwidget_print_char() to make sure the positions are determined accurately. NOT TODO: - Decided not to use glBitmap() with display lists because it would disallow pretty antialiased fonts. git-svn-id: svn://svn.icculus.org/gtkradiant/GtkRadiant/trunk@335 8a3a26a2-13c4-0310-b231-cf6edde360e5
