The Lua applications must also +be modified to include a call to function <font face="Courier New"><strong>cdluaiup_open</strong></font> after +<font face="Courier New"><strong>cdlua_open</strong></font>, and must be linked with the "<strong>cdluaiup</strong>" +library. The SIMULATE driver no longer exists, therefore the applications that used it must be modified to use the new +function, <font face="Courier New"><strong>cdSimulate</strong></font>, without the need for creating a new driver.</p> +<ul> + <li>Changed: the internal structure of the library was changed once again. One of the purposes is to make the + drivers become independent from the function table. With this change, adding a new function to the function table does + not imply editing the old drivers. We also allowed the drivers not to implement functions that do not make sense in + their context. Another modification simplifying the work in the drivers was to bring the attribute query mechanism to + the library's control part, freeing the drivers from this obligation. Taking the chance, we determined that a change + in an attribute to a value equal to the current one will not be effective, thus saving calls to the driver. Now, the + value of an attribute is changed even if the driver function is not implemented, as the driver can query this + attribute later on. The management of default values of the attributes is also done by the library's control part. All + these changes prepare the library to a new philosophy: before, if a driver did not contain a certain feature, it + simply did nothing. The new philosophy will be: if a driver does not contain a certain feature, then the simulation of + this feature will be activated.</li> + <li>Changed: when a canvas which is already active is activated again, an internal driver function is now called, + notifying an update instead of an activation.</li> + <li>Changed: the use of the CD canvas with a IUP canvas is better described in the manual, showing the various + ways of treating the canvas creation prooblem.</li> + <li>Changed: all functions in the control module now have <font face="Courier New">ASSERT</font> directives. Thus, + using the library with depuration information, one can better detect simple errors.</li> + <li>Changed: in order to use the IUP driver, it must be linked with the "<strong>cdiup</strong>" library, apart + from the "<strong>cd</strong>" library (<font face="Courier New">cdiup.lib</font> in Windows, <font face="Courier New"> + cdiuplib.a</font> in UNIX).</li> + <li>Changed: the IMAGERGB driver is now implemented using the simulation functions.</li> + <li>Changed: the <font face="Courier New"><b>cdMark</b></font> function is back to the function table, so that the + drivers in which the primitive can be implemented can profit from it.</li> + <li>Changed: in order to assure that the use of server images is done only between canvases of the same driver, or + of the same basic driver, an internal structure was defined for the server image containing the functions of the + driver from which the image was created. Thus, if the <font face="Courier New"><b>cdKillImage</b></font> function is + called with an active canvas of a different kind from that in which the image was created, the + <font face="Courier New"><b>KillImage</b></font> function of the correct driver will be called.</li> + <li>Changed: in the X-Windows driver, the XV code was used to optimize functions <font face="Courier New"><strong> + cdPutImageRectRGB</strong></font> and <font face="Courier New"><strong>cdPutImageRectMap</strong></font>.</li> + <li>Changed: the Lua binding was updated.

The + <font face="Courier New"><strong>cdBackOpacity</strong></font> function was not implemented. The + <font face="Courier New"><strong>cdFlush</strong></font> function was not preserving the canvas attributes.
