Question:
I don't care about matching the screen size on the target platform, I just want to be able to see more of my OPL source code: how can I make that window bigger?

Answer:
The WINS emulator reads \Epoc32\Data\SYSTEM.INI to look for overrides to the default settings of various parameters [[ this is implemented in E32\KPWINS\KP_GUI.CPP ]]. The current defaults could be achieved explicitly by using

ScreenWidth 640
ScreenHeight 240
ScreenOffsetX 123
ScreenOffsetY 53
FasciaBitmap \Epoc32\Data\Fascia.bmp
CaseBitmap \Epoc32\Data\Case.bmp
LedSize 14
LedOffsetX 60
LedOffsetY 45
LedGap 5
LedArrangeVertically # alternatively, LedArrangeHorizontally
DebugMask 0 # for User::SetDebugMask()
MegabytesOfFreeMemory 0 # use 3 for a 4 Meg machine, or 7 for an 8 Meg machine)
The screen size and position are the position of the emulated LCD within the Fascia bitmap and the fascia bitmap defines the size of the digitiser: the overall window size is big enough for both. If you change any of this, it's probably a good idea to use an app like Paint to produce a new Fascia bitmap which contains the active "buttons" of the original in the new places relative to the changed screen size.

The "MegabytesOfFreeMemory" setting turns on a mechanism which limits the overall memory allocation, matching more closely the behaviour of the real machine. The default value of 0 means "no limit", and can result in the amount of Free memory being reported as a negative value!
Further Answer
The suitable values for MegabytesOfFreeMemory 0, 3, and 7. I tried 1 to get a 2Mb rom and this did not work. I got OOM on boot up.

Try other values at you peril.

Further Answer

You can now also supply the following parameters to \Epoc32\Data\SYSTEM.INI:

PhysicalScreenWidth 7620 # values are in twips,
PhysicalScreenHeight 2858 # (1 twip = 1/1440th of an inch)
