Changeset 108 for trunk/src/gl

Timestamp:

Author:

Message:

• gui_common.hh - render_data did not have virtual destructor - fixed
• position.hh - fixed comparison operators (were not const)
• gl_context - draw will not be done if count = 0 (state will be applied though?)
• gl_context - unpack alignment set to 1 (possibly not needed if careful)

File:

• trunk/src/gl/gl_context.cc (modified) (2 diffs)
