CON: Add drawline256 and drawlinergb commands that call the internal functions used for the automap lines.

drawline256 <x0> <y0> <x1> <y1> <index>
drawlinergb <x0> <y0> <x1> <y1> <index> <rgb>

The coordinates are xdim<<12/ydim<<12 based, not 320<<16x200<<16.
<index> is a palette index, and for drawlinergb is used as a fallback in the software renderer.
<rgb> is encoded the same as PROJ_FLASH_COLOR.

CON: Add getclosestcol command, which finds the closest palette index given

getclosestcol <return> <color> <limit>

<color> is encoded the same as PROJ_FLASH_COLOR.

<limit> is the index of the last palette color that should be considered. Use 255 for the whole palette, 254 to exclude the transparent color, 239 to exclude Duke 3D's fullbrights, etc.

CON: Add EVENT_DISPLAYOVERHEADMAPTEXT.

Set RETURN to any non-zero value to disable hardcoded display of text.

If you wish to replace the hardcoded text, you must check that userdef[].overhead_on == 2 yourself.
