===== BITMAP ENABLE ✓ =====

===== SYNTAX =====
     BITMAP ENABLE ( width, height [, colors ] )
     BITMAP ENABLE ( colors )

==== PURPOSE ====






Enable bitmap graphics on the target machine. Bitmap resolution and colors depends on hardware.
Enabling the bitmap also sets the starting address in memory, for those computers that have 
graphics mapped in memory. 

Given the great variety of hardware that ugBASIC supports and the isomorphic approach adopted, 
this commands can be used to require a specific resolution, color depth and other characteristics in a
hardware independent way. 

In this regard, the following approach has been adopted. It is possible to ask for specific 
chacteristics, such as height and width of the screen. However ugBASIC will choose the closest 
resolution, based on the hardware on which it will runs.

Likewise, if no type of resolution constraint is set, the best is offered.

To change resolution and colors, you can use the ''([width],[height],[colors])'', ''([width],[height])'' 
or the ''([colors])'' syntax after ''BITMAP ENABLE'' command. So, if you omit a parameters, it means that
it is not important to set.
